USN-2158-1: Linux kernel (Raring HWE) vulnerabilities
1 April 2014
Several security issues were fixed in the kernel.
Releases
Packages
- linux-lts-raring - Linux hardware enablement kernel from Raring
Details
Stephan Mueller reported an error in the Linux kernel's ansi cprng random
number generator. This flaw makes it easier for a local attacker to break
cryptographic protections. (CVE-2013-4345)
Nico Golde and Fabian Yamaguchi reported buffer underflow errors in the
implementation of the XFS filesystem in the Linux kernel. A local user with
CAP_SYS_ADMIN could exploit these flaw to cause a denial of service (memory
corruption) or possibly other unspecified issues. (CVE-2013-6382)
An information leak was discovered in the Linux kernel when built with the
NetFilter Connection Tracking (NF_CONNTRACK) support for IRC protocol
(NF_NAT_IRC). A remote attacker could exploit this flaw to obtain
potentially sensitive kernel information when communicating over a client-
to-client IRC connection(/dcc) via a NAT-ed network. (CVE-2014-1690)
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 12.04
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. If
you use linux-restricted-modules, you have to update that package as
well to get modules which work with the new kernel version. Unless you
manually uninstalled the standard kernel metapackages (e.g. linux-generic,
linux-server, linux-powerpc), a standard system upgrade will automatically
perform this as well.
