Ubuntu Security Notice USN-2137-1
March 07, 2014
linux-lts-saucy vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
– Ubuntu 12.04 LTS
Summary:
Several security issues were fixed in the kernel.
Software Description:
– linux-lts-saucy: Linux hardware enablement kernel from Saucy
Details:
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)
Matthew Thode reported a denial of service vulnerability in the Linux
kernel when SELinux support is enabled. A local user with the CAP_MAC_ADMIN
capability (and the SELinux mac_admin permission if running in enforcing
mode) could exploit this flaw to cause a denial of service (kernel crash).
(CVE-2014-1874)
An information leak was discovered in the Linux kernel’s NFS filesystem. A
local users with write access to an NFS share could exploit this flaw to
obtain potential sensative information from kernel memory. (CVE-2014-2038)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 12.04 LTS:
linux-image-3.11.0-18-generic 3.11.0-18.32~precise1
linux-image-3.11.0-18-generic-lpae 3.11.0-18.32~precise1
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.
