TITLE

Linux Kernel CVE-2017-7895 Multiple Security Bypass Vulnerabilities

DESCRIPTION

The NFSv2 and NFSv3 server implementations in the Linux kernel through 4.10.13 lack certain checks for the end of a buffer, which allows remote attackers to trigger pointer-arithmetic errors or possibly have unspecified other impact via crafted requests, related to fs/nfsd/nfs3xdr.c and fs/nfsd/nfsxdr.c. Linux Kernel is prone to multiple security-bypass vulnerabilities. Attackers can exploit these issues to bypass certain security restrictions and perform unauthorized actions. This may aid in further attacks. 6.2) - x86_64 3. On systems with the stack protection feature enabled in the kernel (CONFIG_CC_STACKPROTECTOR=y, which is enabled on all architectures other than s390x and ppc64[le]), an unauthenticated attacker able to initiate a connection to a system via Bluetooth could use this flaw to crash the system. Due to the nature of the stack protection feature, code execution cannot be fully ruled out, although we believe it is unlikely. Bug Fix(es): * Previously, while the MAP_GROWSDOWN flag was set, writing to the memory which was mapped with the mmap system call failed with the SIGBUS signal. (BZ#1474720) 4. CVE-2017-7487 Li Qiang reported a reference counter leak in the ipxitf_ioctl function which may result into a use-after-free vulnerability, triggerable when a IPX interface is configured. CVE-2017-7645 Tuomas Haanpaa and Matti Kamunen from Synopsys Ltd discovered that the NFSv2 and NFSv3 server implementations are vulnerable to an out-of-bounds memory access issue while processing arbitrarily long arguments sent by NFSv2/NFSv3 PRC clients, leading to a denial of service. A remote attacker with write access to a NFS mount can take advantage of this flaw to read chunks of arbitrary memory from both kernel-space and user-space. CVE-2017-8064 Arnd Bergmann found that the DVB-USB core misused the device logging system, resulting in a use-after-free vulnerability, with unknown security impact. CVE-2017-8925 Johan Hovold found a reference counter leak in the omninet USB serial driver, resulting in a use-after-free vulnerability. This can be triggered by a local user permitted to open tty devices. CVE-2017-9074 Andrey Konovalov reported that the IPv6 fragmentation implementation could read beyond the end of a packet buffer. CVE-2017-9075 Andrey Konovalov reported that the SCTP/IPv6 implementation wrongly initialised address lists on connected sockets, resulting in a use-after-free vulnerability, a similar issue to CVE-2017-8890. This can be triggered by any local user. CVE-2017-9076 / CVE-2017-9077 Cong Wang found that the TCP/IPv6 and DCCP/IPv6 implementations wrongly initialised address lists on connected sockets, a similar issue to CVE-2017-9075. CVE-2017-9242 Andrey Konovalov reported a packet buffer overrun in the IPv6 implementation. CVE-2017-1000364 The Qualys Research Labs discovered that the size of the stack guard page is not sufficiently large. The stack-pointer can jump over the guard-page and moving from the stack into another memory region without accessing the guard-page. In this case no page-fault exception is raised and the stack extends into the other memory region. An attacker can exploit this flaw for privilege escalation. The default stack gap protection is set to 256 pages and can be configured via the stack_guard_gap kernel parameter on the kernel command line. Further details can be found at https://www.qualys.com/2017/06/19/stack-clash/stack-clash.txt For the oldstable distribution (jessie), these problems have been fixed in version 3.16.43-2+deb8u1. For the stable distribution (stretch), these problems have been fixed in version 4.9.30-2+deb9u1 or earlier versions before the stretch release. =========================================================================== Ubuntu Security Notice USN-3312-2 June 07, 2017 linux-lts-xenial vulnerabilities =========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 14.04 LTS Summary: Several security issues were fixed in the Linux kernel. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu 14.04 LTS. It was discovered that the netfilter netlink implementation in the Linux kernel did not properly validate batch messages.

(CVE-2016-8632) It was discovered that the keyring implementation in the Linux kernel in some situations did not prevent special internal keyrings from being joined by userspace keyrings. A privileged local attacker could use this to bypass module verification. A privileged local attacker could use this to execute arbitrary code. (CVE-2017-0605) Dmitry Vyukov discovered that KVM implementation in the Linux kernel improperly emulated the VMXON instruction. A local attacker in a guest OS could use this to cause a denial of service (memory consumption) in the host OS. (CVE-2017-2596) Daniel Jiang discovered that a race condition existed in the ipv4 ping socket implementation in the Linux kernel. A local privileged attacker could use this to cause a denial of service (system crash). (CVE-2017-2671) Di Shen discovered that a race condition existed in the perf subsystem of the Linux kernel. A local attacker could use this to cause a denial of service or possibly gain administrative privileges. (CVE-2017-6001) Eric Biggers discovered a memory leak in the keyring implementation in the Linux kernel. A local attacker could use this to cause a denial of service (memory consumption). (CVE-2017-7472) Sabrina Dubroca discovered that the asynchronous cryptographic hash (ahash) implementation in the Linux kernel did not properly handle a full request queue. A local attacker could use this to cause a denial of service (infinite recursion). A remote attacker could use this to cause a denial of service (system crash). (CVE-2017-7645) Tommi Rantala and Brad Spengler discovered that the memory manager in the Linux kernel did not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism. A local attacker with access to /dev/mem could use this to expose sensitive information or possibly execute arbitrary code. (CVE-2017-7895) It was discovered that a use-after-free vulnerability existed in the device driver for XCeive xc2028/xc3028 tuners in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2016-7913) Vlad Tsyrklevich discovered an integer overflow vulnerability in the VFIO PCI driver for the Linux kernel. A local attacker with access to a vfio PCI device file could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2016-9083, CVE-2016-9084) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 14.04 LTS: linux-image-4.4.0-79-generic 4.4.0-79.100~14.04.1 linux-image-4.4.0-79-generic-lpae 4.4.0-79.100~14.04.1 linux-image-4.4.0-79-lowlatency 4.4.0-79.100~14.04.1 linux-image-4.4.0-79-powerpc-e500mc 4.4.0-79.100~14.04.1 linux-image-4.4.0-79-powerpc-smp 4.4.0-79.100~14.04.1 linux-image-4.4.0-79-powerpc64-emb 4.4.0-79.100~14.04.1 linux-image-4.4.0-79-powerpc64-smp 4.4.0-79.100~14.04.1 linux-image-generic-lpae-lts-xenial 4.4.0.79.64 linux-image-generic-lts-xenial 4.4.0.79.64 linux-image-lowlatency-lts-xenial 4.4.0.79.64 linux-image-powerpc-e500mc-lts-xenial 4.4.0.79.64 linux-image-powerpc-smp-lts-xenial 4.4.0.79.64 linux-image-powerpc64-emb-lts-xenial 4.4.0.79.64 linux-image-powerpc64-smp-lts-xenial 4.4.0.79.64 After a standard system update you need to reboot your computer to make all the necessary changes. ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: kernel security and bug fix update Advisory ID: RHSA-2017:1723-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2017:1723 Issue date: 2017-07-11 CVE Names: CVE-2017-7895 ===================================================================== 1. Summary: An update for kernel is now available for Red Hat Enterprise Linux 6. 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 Desktop (v. 6) - i386, noarch, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - noarch, x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, noarch, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, noarch, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64 3. (CVE-2017-7895, Important) Red Hat would like to thank Ari Kauppi for reporting this issue. Bug Fix(es): * If several file operations were started after a mounted NFS share had got idle and its Transmission Control Protocol (TCP) connection had therefore been terminated, these operations could cause multiple TCP SYN packets coming from the NFS client instead of one. With this update, the reconnection logic has been fixed, and only one TCP SYN packet is now sent in the described situation. (BZ#1450850) * When the ixgbe driver was loaded for a backplane-connected network card, a kernel panic could occur, because the ops.setup_fc function pointer was used before the initialization. With this update, ops.setup_fc is initialized earlier. As a result, ixgbe no longer panics on load. (BZ#1457347) * When setting an Access Control List (ACL) with 190 and more Access Control Entries (ACEs) on a NFSv4 directory, a kernel crash could previously occur. This update fixes the nfs4_getfacl() function, and the kernel no longer crashes under the described circumstances. (BZ#1449096) * When upgrading to kernel with the fix for stack guard flaw, a crash could occur in Java Virtual Machine (JVM) environments, which attempted to implement their own stack guard page. With this update, the underlying source code has been fixed to consider the PROT_NONE mapping as a part of the stack, and the crash in JVM no longer occurs under the described circumstances. (BZ#1466667) * When a program receives IPv6 packets using the raw socket, the ioctl(FIONREAD) and ioctl(SIOCINQ) functions can incorrectly return zero waiting bytes. This update fixes the ip6_input_finish() function to check the raw payload size properly. As a result, the ioctl() function now returns bytes waiting in the raw socket correctly. (BZ#1450870) * Previously, listing a directory on a non-standard XFS filesystem (with non-default multi-fsb directory blocks) could lead to a soft lock up due to array index overrun in the xfs_dir2_leaf_readbuf() function. This update fixes xfs_dir2_leaf_readbuf(), and the soft lock up no longer occurs under the described circumstances. (BZ#1445179) * Previously, aborts from the array after the Storage Area Network (SAN) fabric back-pressure led to premature reuse of still valid sequence with the same OX_ID. Consequently, an error message and data corruption could occur. This update fixes the libfc driver to isolate the timed out OX_IDs, thus fixing this bug. (BZ#1455550) * Previously, a kernel panic occurred when the mcelog daemon executed a huge page memory offline. This update fixes the HugeTLB feature of the Linux kernel to check for the Page Table Entry (PTE) NULL pointer in the page_check_address() function. As a result, the kernel panic no longer occurs under the described circumstances. (BZ#1444351) 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.
