Package : iceweasel
CVE ID : CVE-2014-8634 CVE-2014-8638 CVE-2014-8639 CVE-2014-8641

Multiple security issues have been found in Iceweasel, Debian's version
of the Mozilla Firefox web browser: Multiple memory safety errors
and implementation errors may lead to the execution of arbitrary code,
information leaks or denial of service.

For the stable distribution (wheezy), these problems have been fixed in
version 31.4.0esr-1~deb7u1.

For the unstable distribution (sid), these problems have been fixed in
version 31.4.0esr-1.

We recommend that you upgrade your iceweasel packages.

[DSA 3128-1] linux security update

Package : linux
CVE ID : CVE-2013-6885 CVE-2014-8133 CVE-2014-9419 CVE-2014-9529
CVE-2014-9584

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
http://support.amd.com/TechDocs/51810_16h_00h-0Fh_Rev_Guide.pdf

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.

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.

We recommend that you upgrade your linux packages.
