Debian DSA-3128-1 : linux - security update

high Nessus Plugin ID 80558
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Debian host is missing a security-related update.


Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or information leaks.

- CVE-2013-6885 It was discovered that under specific circumstances, a combination of write operations to write-combined memory and locked CPU instructions may cause a core hang on AMD 16h 00h through 0Fh processors. A local user can use this flaw to mount a denial of service (system hang) via a crafted application.

For more information please refer to the AMD CPU erratum 793 in

- CVE-2014-8133 It was found that the espfix funcionality can be bypassed by installing a 16-bit RW data segment into GDT instead of LDT (which espfix checks for) and using it for stack. A local unprivileged user could potentially use this flaw to leak kernel stack addresses and thus allowing to bypass the ASLR protection mechanism.

- CVE-2014-9419 It was found that on Linux kernels compiled with the 32 bit interfaces (CONFIG_X86_32) a malicious user program can do a partial ASLR bypass through TLS base addresses leak when attacking other programs.

- CVE-2014-9529 It was discovered that the Linux kernel is affected by a race condition flaw when doing key garbage collection, allowing local users to cause a denial of service (memory corruption or panic).

- CVE-2014-9584 It was found that the Linux kernel does not validate a length value in the Extensions Reference (ER) System Use Field, which allows local users to obtain sensitive information from kernel memory via a crafted iso9660 image.


Upgrade the linux packages.

For the stable distribution (wheezy), these problems have been fixed in version 3.2.65-1+deb7u1. Additionally this update fixes a suspend/resume regression introduced with 3.2.65.

For the upcoming stable distribution (jessie) and the unstable distribution (sid), these problems will be fixed soon.
