CVE-2017-5753

TITLE

CPU hardware utilizing speculative execution may be vulnerable to cache side-channel attacks

DESCRIPTION

Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis. Two vulnerabilities are identified, known as "Variant 3a" and "Variant 4". CPUhardware is a set of firmware that runs in the CPU (Central Processing Unit) for managing and controlling the CPU. The Meltdown vulnerability exists in the CPU processor core, which \"melts\" the security boundary implemented by hardware, allowing low-privileged user-level applications to \"cross-border\" access to system-level memory, causing data leakage. Multiple CPU Hardware are prone to an information-disclosure vulnerability. Attackers can exploit this issue to obtain sensitive information that may aid in further attacks. The following products and versions are affected: ARM Cortex-R7; Cortex-R8; Cortex-A8; Cortex-A9; Cortex-A12; Xeon CPU E5-1650 v3, v2, v4; Xeon E3-1265l v2, v3, v4 ; Xeon E3-1245 v2, v3, v5, v6 versions; Xeon X7542, etc. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 - ------------------------------------------------------------------------- Debian Security Advisory DSA-4188-1 security@debian.org https://www.debian.org/security/ Salvatore Bonaccorso May 01, 2018 https://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : linux CVE ID : CVE-2017-5715 CVE-2017-5753 CVE-2017-17975 CVE-2017-18193 CVE-2017-18216 CVE-2017-18218 CVE-2017-18222 CVE-2017-18224 CVE-2017-18241 CVE-2017-18257 CVE-2018-1065 CVE-2018-1066 CVE-2018-1068 CVE-2018-1092 CVE-2018-1093 CVE-2018-1108 CVE-2018-5803 CVE-2018-7480 CVE-2018-7566 CVE-2018-7740 CVE-2018-7757 CVE-2018-7995 CVE-2018-8087 CVE-2018-8781 CVE-2018-8822 CVE-2018-10323 CVE-2018-1000199 Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. CVE-2017-5715 Multiple researchers have discovered a vulnerability in various processors supporting speculative execution, enabling an attacker controlling an unprivileged process to read memory from arbitrary addresses, including from the kernel and all other processes running on the system. This specific attack has been named Spectre variant 2 (branch target injection) and is mitigated for the x86 architecture (amd64 and i386) by using the "retpoline" compiler feature which allows indirect branches to be isolated from speculative execution. CVE-2017-5753 Multiple researchers have discovered a vulnerability in various processors supporting speculative execution, enabling an attacker controlling an unprivileged process to read memory from arbitrary addresses, including from the kernel and all other processes running on the system. This specific attack has been named Spectre variant 1 (bounds-check bypass) and is mitigated by identifying vulnerable code sections (array bounds checking followed by array access) and replacing the array access with the speculation-safe array_index_nospec() function. More use sites will be added over time. CVE-2017-17975 Tuba Yavuz reported a use-after-free flaw in the USBTV007 audio-video grabber driver. A local user could use this for denial of service by triggering failure of audio registration. CVE-2017-18193 Yunlei He reported that the f2fs implementation does not properly handle extent trees, allowing a local user to cause a denial of service via an application with multiple threads. CVE-2017-18216 Alex Chen reported that the OCFS2 filesystem failed to hold a necessary lock during nodemanager sysfs file operations, potentially leading to a null pointer dereference. A local user could use this for denial of service. CVE-2017-18218 Jun He reported a user-after-free flaw in the Hisilicon HNS ethernet driver. A local user could use this for denial of service. CVE-2017-18222 It was reported that the Hisilicon Network Subsystem (HNS) driver implementation does not properly handle ethtool private flags. A local user could use this for denial of service or possibly have other impact. CVE-2017-18224 Alex Chen reported that the OCFS2 filesystem omits the use of a semaphore and consequently has a race condition for access to the extent tree during read operations in DIRECT mode. A local user could use this for denial of service. CVE-2017-18241 Yunlei He reported that the f2fs implementation does not properly initialise its state if the "noflush_merge" mount option is used. A local user with access to a filesystem mounted with this option could use this to cause a denial of service. CVE-2017-18257 It was reported that the f2fs implementation is prone to an infinite loop caused by an integer overflow in the __get_data_block() function. A local user can use this for denial of service via crafted use of the open and fallocate system calls with an FS_IOC_FIEMAP ioctl. CVE-2018-1065 The syzkaller tool found a NULL pointer dereference flaw in the netfilter subsystem when handling certain malformed iptables rulesets. A local user with the CAP_NET_RAW or CAP_NET_ADMIN capability (in any user namespace) could use this to cause a denial of service. Debian disables unprivileged user namespaces by default. CVE-2018-1066 Dan Aloni reported to Red Hat that the CIFS client implementation would dereference a null pointer if the server sent an invalid response during NTLMSSP setup negotiation. This could be used by a malicious server for denial of service. CVE-2018-1068 The syzkaller tool found that the 32-bit compatibility layer of ebtables did not sufficiently validate offset values. On a 64-bit kernel, a local user with the CAP_NET_ADMIN capability (in any user namespace) could use this to overwrite kernel memory, possibly leading to privilege escalation. Debian disables unprivileged user namespaces by default. CVE-2018-1092 Wen Xu reported that a crafted ext4 filesystem image would trigger a null dereference when mounted. A local user able to mount arbitrary filesystems could use this for denial of service. CVE-2018-1093 Wen Xu reported that a crafted ext4 filesystem image could trigger an out-of-bounds read in the ext4_valid_block_bitmap() function. A local user able to mount arbitrary filesystems could use this for denial of service. CVE-2018-1108 Jann Horn reported that crng_ready() does not properly handle the crng_init variable states and the RNG could be treated as cryptographically safe too early after system boot. CVE-2018-5803 Alexey Kodanev reported that the SCTP protocol did not range-check the length of chunks to be created. A local or remote user could use this to cause a denial of service. CVE-2018-7480 Hou Tao discovered a double-free flaw in the blkcg_init_queue() function in block/blk-cgroup.c. A local user could use this to cause a denial of service or have other impact. CVE-2018-7566 Fan LongFei reported a race condition in the ALSA (sound) sequencer core, between write and ioctl operations. This could lead to an out-of-bounds access or use-after-free. A local user with access to a sequencer device could use this for denial of service or possibly for privilege escalation. CVE-2018-7740 Nic Losby reported that the hugetlbfs filesystem's mmap operation did not properly range-check the file offset. A local user with access to files on a hugetlbfs filesystem could use this to cause a denial of service. CVE-2018-7757 Jason Yan reported a memory leak in the SAS (Serial-Attached SCSI) subsystem. A local user on a system with SAS devices could use this to cause a denial of service. CVE-2018-7995 Seunghun Han reported a race condition in the x86 MCE (Machine Check Exception) driver. This is unlikely to have any security impact. CVE-2018-8087 A memory leak flaw was found in the hwsim_new_radio_nl() function in the simulated radio testing tool driver for mac80211, allowing a local user to cause a denial of service. CVE-2018-8781 Eyal Itkin reported that the udl (DisplayLink) driver's mmap operation did not properly range-check the file offset. A local user with access to a udl framebuffer device could exploit this to overwrite kernel memory, leading to privilege escalation. CVE-2018-8822 Dr Silvio Cesare of InfoSect reported that the ncpfs client implementation did not validate reply lengths from the server. An ncpfs server could use this to cause a denial of service or remote code execution in the client. CVE-2018-10323 Wen Xu reported a NULL pointer dereference flaw in the xfs_bmapi_write() function triggered when mounting and operating a crafted xfs filesystem image. A local user able to mount arbitrary filesystems could use this for denial of service. CVE-2018-1000199 Andy Lutomirski discovered that the ptrace subsystem did not sufficiently validate hardware breakpoint settings. Local users can use this to cause a denial of service, or possibly for privilege escalation, on x86 (amd64 and i386) and possibly other architectures. For the stable distribution (stretch), these problems have been fixed in version 4.9.88-1. We recommend that you upgrade your linux packages.

By now, we're sure most everyone have heard of the Meltdown and Spectre attacks. If not, head over to https://meltdownattack.com/ and get an overview. https://googleprojectzero.blogspot.com/2018/01/reading-privileged-memory-with-side.html The FreeBSD Security Team was notified of the issue in late December and received a briefing under NDA with the original embargo date of January 9th. Since we received relatively late notice of the issue, our ability to provide fixes is delayed. Meltdown (CVE-2017-5754) ~~~~~~~~~~~~~~~~~~~~~~~~ In terms of priority, the first step is to mitigate against the Meltdown attack (CVE-2017-5754, cited as variant 3 by Project Zero). Work for this is ongoing, but due to the relatively large changes needed, this is going to take a little while. We are currently targeting patches for amd64 being dev complete this week with testing probably running into next week. From there, we hope to give it a short bake time before pushing it into the 11.1-RELEASE branch. Additional work will be required to bring the mitigation to 10.3-RELEASE and 10.4-RELEASE. The code will be selectable via a tunable which will automatically turn on for modern Intel processors and off for AMD processors (since they are reportedly not vulnerable). Since the fix for Meltdown does incur a performance hit for any transition between user space and kernel space, this could be rather impactful depending on the workload. As such, the tunable can also be overridden by the end-user if they are willing to accept the risk. Initial work can be tracked at https://reviews.freebsd.org/D13797. Please note this is a work in progress and some stuff is likely to be broken. Spectre (CVE-2017-5753 and CVE-2017-5715) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ When it comes to the Spectre vulnerabilities, it is much harder to sort these out. Variant 1 (CVE-2017-5753) is going to require some static analysis to determine vulnerable use cases that will require barriers to stop speculation from disclosing information it shouldn't. While we haven't done the analysis to determine where we are vulnerable, the number of cases here are supposed to be pretty small. Apparently there have been some Coverity rules developed to help look for these, but we are still evaluating what can be done here. The other half of Spectre, variant 2 (CVE-2017-5715) is a bit trickier as it affects both normal processes and bhyve. There is a proposed patch for LLVM (https://reviews.llvm.org/D41723) that introduces a concept called 'retpoline' which mitigates this issue. We are likely to pull this into HEAD and 11-STABLE once it hits the LLVM tree. Unfortunately, the currently supported FreeBSD releases are using older versions of LLVM for which we are not sure the LLVM project will produce patches. We will be looking at the feasibility to backport these patches to these earlier versions. There are CPU microcode fixes coming out when in concert with OS changes would also help, but that's a bit down the road at the moment.

This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu 14.04 LTS. (CVE-2017-5715, CVE-2017-5753) USN-3522-2 mitigated CVE-2017-5754 (Meltdown) for the amd64 architecture in the Linux Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu 14.04 LTS. This flaw is known as Meltdown. (CVE-2017-5754) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 14.04 LTS: linux-image-4.4.0-1011-aws 4.4.0-1011.11 linux-image-4.4.0-111-generic 4.4.0-111.134~14.04.1 linux-image-4.4.0-111-lowlatency 4.4.0-111.134~14.04.1 linux-image-4.4.0-111-powerpc-e500mc 4.4.0-111.134~14.04.1 linux-image-4.4.0-111-powerpc-smp 4.4.0-111.134~14.04.1 linux-image-4.4.0-111-powerpc64-emb 4.4.0-111.134~14.04.1 linux-image-4.4.0-111-powerpc64-smp 4.4.0-111.134~14.04.1 linux-image-aws 4.4.0.1011.11 linux-image-generic-lts-xenial 4.4.0.111.95 linux-image-lowlatency-lts-xenial 4.4.0.111.95 linux-image-powerpc-e500mc-lts-xenial 4.4.0.111.95 linux-image-powerpc-smp-lts-xenial 4.4.0.111.95 linux-image-powerpc64-emb-lts-xenial 4.4.0.111.95 linux-image-powerpc64-smp-lts-xenial 4.4.0.111.95 Please note that fully mitigating CVE-2017-5715 (Spectre Variant 2) requires corresponding processor microcode/firmware updates or, in virtual environments, hypervisor updates. Ubuntu is working with Intel and AMD to provide future microcode updates that implement IBRS and IBPB as they are made available. Ubuntu users with a processor from a different vendor should contact the vendor to identify necessary firmware updates. Ubuntu will provide corresponding QEMU updates in the future for users of self-hosted virtual environments in coordination with upstream QEMU. Ubuntu users in cloud environments should contact the cloud provider to confirm that the hypervisor has been updated to expose the new CPU features to virtual machines. Relevant releases/architectures: RHEL 7-based RHEV-H - noarch 3. Description: The ovirt-node-ng packages provide the Red Hat Virtualization Host. These packages include redhat-release-virtualization-host, ovirt-node, and rhev-hypervisor. RHVH features a Cockpit user interface for monitoring the host's resources and performing administrative tasks. Summary: An update for kernel is now available for Red Hat Enterprise Linux 6.7 Extended Update Support. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux HPC Node EUS (v. 6.7) - noarch, x86_64 Red Hat Enterprise Linux HPC Node Optional EUS (v. 6.7) - x86_64 Red Hat Enterprise Linux Server EUS (v. 6.7) - i386, noarch, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional EUS (v. 6.7) - i386, ppc64, s390x, x86_64 3. Security Fix(es): An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimization). There are three primary variants of the issue which differ in the way the speculative execution can be exploited. Note: This issue is present in hardware and cannot be fully fixed via software update. The updated kernel packages provide software mitigation for this hardware issue at a cost of potential performance penalty. Please refer to References section for further information about this issue and the performance impact. In this update mitigations for x86-64 architecture are provided. Variant CVE-2017-5753 triggers the speculative execution by performing a bounds-check bypass. It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory accesses may cause allocation into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to cross the syscall boundary and read privileged memory by conducting targeted cache side-channel attacks. It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory accesses may cause allocation into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to cross the syscall and guest/host boundaries and read privileged memory by conducting targeted cache side-channel attacks. (CVE-2017-5715, Important) Variant CVE-2017-5754 relies on the fact that, on impacted microprocessors, during speculative execution of instruction permission faults, exception generation triggered by a faulting access is suppressed until the retirement of the whole instruction block. In a combination with the fact that memory accesses may populate the cache even when the block is being dropped and never committed (executed), an unprivileged local attacker could use this flaw to read privileged (kernel space) memory by conducting targeted cache side-channel attacks. (CVE-2017-5754, Important) Note: CVE-2017-5754 affects Intel x86-64 microprocessors. AMD x86-64 microprocessors are not affected by this issue. Red Hat would like to thank Google Project Zero for reporting these issues. 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 The system must be rebooted for this update to take effect. 5.

Intel has now identified the root cause of these issues and determined that these microcodes may introduce reboots and other unpredictable system behavior. Due to the severity of the potential issues that may occur when using these microcodes, Intel is now recommending that customers discontinue their use. Additional information is available from Intels Security Exploit Newsroom here: <https://newsroom.intel.com/press-kits/security-exploits-intel-products/> . HPE is in alignment with Intel in our recommendation that customers discontinue use of System ROMs including impacted microcodes and revert to earlier System ROM versions. All System ROMs including impacted microcodes have been removed from the HPE Support Site. This impacts HPE ProLiant and Synergy Gen10, Gen9, and Gen8 v2 servers as well as HPE Superdome servers for which updated System ROMs had previously been made available. Intel is working on updated microcodes to address these issues, and HPE will validate updated System ROMs including these microcodes and make them available to our customers in the coming weeks. Mitigations for Variant 1 (Spectre) and Variant 3 (Meltdown) vulnerabilities require only OS updates and are not impacted. * HPE has provided a customer bulletin <https://support.hpe.com/hpsc/doc/public/display?docId=emr_na-a00039267en_us> with specific instructions to obtain the udpated sytem ROM - Note: + CVE-2017-5715 (Variant 2) requires that the System ROM be updated and a vendor supplied operating system update be applied as well. + For CVE-2017-5753, CVE-2017-5754 (Variants 1 and 3) require only updates of a vendor supplied operating system. + HPE will continue to add additional products to the list.
