CVE-2018-3620

TITLE

Intel processors are vulnerable to a speculative execution side-channel attack called L1 Terminal Fault (L1TF)

DESCRIPTION

Systems with microprocessors utilizing speculative execution and address translations may allow unauthorized disclosure of information residing in the L1 data cache to an attacker with local user access via a terminal page fault and a side-channel analysis. These attacks are known as L1 Terminal Fault: SGX, L1 Terminal Fault: OS/SMM, and L1 Terminal Fault: VMM. Intel Core i3 processor, etc. are all CPU (central processing unit) products of Intel Corporation of the United States. Security vulnerabilities exist in several Intel products that use speculative execution and address translation. The following products are affected: Intel Core i3 processor; Intel Core i5 processor; Intel Core i7 processor; Intel Core M processor family; 2nd generation Intel Core processors; 3rd generation Intel Core processors; 4th generation Intel Core processors; 5th generation Intel Core processors, etc. (CVE-2018-5390) Juha-Matti Tilli discovered that the IP implementation in the Linux kernel performed algorithmically expensive operations in some situations when handling incoming packet fragments. (CVE-2018-5391) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 14.04 LTS: linux-image-3.13.0-155-generic 3.13.0-155.205 linux-image-3.13.0-155-generic-lpae 3.13.0-155.205 linux-image-3.13.0-155-lowlatency 3.13.0-155.205 linux-image-3.13.0-155-powerpc-e500 3.13.0-155.205 linux-image-3.13.0-155-powerpc-e500mc 3.13.0-155.205 linux-image-3.13.0-155-powerpc-smp 3.13.0-155.205 linux-image-3.13.0-155-powerpc64-emb 3.13.0-155.205 linux-image-3.13.0-155-powerpc64-smp 3.13.0-155.205 linux-image-generic 3.13.0.155.165 linux-image-generic-lpae 3.13.0.155.165 linux-image-lowlatency 3.13.0.155.165 linux-image-powerpc-e500 3.13.0.155.165 linux-image-powerpc-e500mc 3.13.0.155.165 linux-image-powerpc-smp 3.13.0.155.165 linux-image-powerpc64-emb 3.13.0.155.165 linux-image-powerpc64-smp 3.13.0.155.165 Please note that the recommended mitigation for CVE-2018-3646 involves updating processor microcode in addition to updating the kernel; however, the kernel includes a fallback for processors that have not received microcode updates. 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. The microcode updates mentioned there are not yet available in a form distributable by Debian. For the stable distribution (stretch), these problems have been fixed in version 4.8.4+xsa273+shim4.10.1+xsa273-1+deb9u10. We recommend that you upgrade your xen packages.

Description: The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * Modern operating systems implement virtualization of physical memory to efficiently use available system resources and provide inter-domain protection through access control and isolation. The L1TF issue was found in the way the x86 microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimisation) in combination with handling of page-faults caused by terminated virtual to physical address resolving process. As a result, an unprivileged attacker could use this flaw to read privileged memory of the kernel or other processes and/or cross guest/host boundaries to read host memory by conducting targeted cache side-channel attacks. (CVE-2018-3620, CVE-2018-3646) * kernel: kvm: vmx: host GDT limit corruption (CVE-2018-10901) For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.

Corrected: 2018-08-14 17:51:12 UTC (stable/11, 11.1-STABLE) 2018-08-15 02:30:11 UTC (releng/11.2, 11.2-RELEASE-p2) 2018-08-15 02:30:11 UTC (releng/11.1, 11.1-RELEASE-p13) CVE Name: CVE-2018-3620, CVE-2018-3646 Special Note: Speculative execution vulnerability mitigation remains a work in progress. This advisory addresses the issue in FreeBSD 11.1 and later. We expect to update this advisory to include 10.4 at a later time. For general information regarding FreeBSD Security Advisories, including descriptions of the fields above, security branches, and the following sections, please visit <URL:https://security.FreeBSD.org/>. I. Background When a program accesses data in memory via a logical address it is translated to a physical address in RAM by the CPU. Accessing an unmapped logical address results in what is known as a terminal fault. II. The CPU may speculatively access the level 1 data cache (L1D). Data which would otherwise be protected may then be determined by using side channel methods. This issue affects bhyve on FreeBSD/amd64 systems. III. Impact An attacker executing user code, or kernel code inside of a virtual machine, may be able to read secret data from the kernel or from another virtual machine. IV. Workaround No workaround is available. V. Solution Upgrade your vulnerable system to a supported FreeBSD stable or release / security branch (releng) dated after the correction date, and reboot. Perform one of the following: 1) To update your vulnerable system via a binary patch: Systems running a RELEASE version of FreeBSD on the i386 or amd64 platforms can be updated via the freebsd-update(8) utility: # freebsd-update fetch # freebsd-update install # shutdown -r +30 "Rebooting for security update" 2) To update your vulnerable system via a source code patch: The following patches have been verified to apply to the applicable FreeBSD release branches. a) Download the relevant patch from the location below, and verify the detached PGP signature using your PGP utility. [FreeBSD 11.2] # fetch https://security.FreeBSD.org/patches/SA-18:09/l1tf-11.2.patch # fetch https://security.FreeBSD.org/patches/SA-18:09/l1tf-11.2.patch.asc # gpg --verify l1tf-11.2.patch.asc [FreeBSD 11.1] # fetch https://security.FreeBSD.org/patches/SA-18:09/l1tf-11.1.patch # fetch https://security.FreeBSD.org/patches/SA-18:09/l1tf-11.1.patch.asc # gpg --verify l1tf-11.1.patch.asc b) Apply the patch. Execute the following commands as root: # cd /usr/src # patch < /path/to/patch c) Recompile your kernel as described in <URL:https://www.FreeBSD.org/handbook/kernelconfig.html> and reboot the system. VI. Correction details CVE-2018-3620 (L1 Terminal Fault-OS) - ------------------------------------ FreeBSD reserves the the memory page at physical address 0, so it will not contain secret data. FreeBSD zeros the paging data structures for unmapped addresses, so that speculatively executed L1 Terminal Faults will access only the reserved, unused page. The following list contains the correction revision numbers for each affected branch.

(CVE-2018-3620) It was discovered that the paravirtualization implementation in the Linux kernel did not properly handle some indirect calls, reducing the effectiveness of Spectre v2 mitigations for paravirtual guests. A local attacker could use this to expose sensitive information. (CVE-2018-15594) It was discovered that memory present in the L1 data cache of an Intel CPU core may be exposed to a malicious process that is executing on the CPU core. A local attacker in a guest virtual machine could use this to expose sensitive information (memory from other guests or the host OS). A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-6555) It was discovered that a stack-based buffer overflow existed in the iSCSI target implementation of the Linux kernel. A remote attacker could use this to cause a denial of service (system crash). (CVE-2018-14633) It was discovered that microprocessors utilizing speculative execution and prediction of return addresses via Return Stack Buffer (RSB) may allow unauthorized memory reads via sidechannel attacks. An attacker could use this to expose sensitive information. (CVE-2018-15572) Jann Horn discovered that the vmacache subsystem did not properly handle sequence number overflows, leading to a use-after-free vulnerability.
