Ubuntu Security Notice USN-2261-1
June 27, 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:
Salva Peiró discovered an information leak in the Linux kernel’s media-
device driver. A local attacker could exploit this flaw to obtain sensitive
information from kernel memory. (CVE-2014-1739)
A bounds check error was discovered in the socket filter subsystem of the
Linux kernel. A local user could exploit this flaw to cause a denial of
service (system crash) via crafted BPF instructions. (CVE-2014-3144)
A remainder calculation error was discovered in the socket filter subsystem
of the Linux kernel. A local user could exploit this flaw to cause a denial
of service (system crash) via crafted BPF instructions. (CVE-2014-3145)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 12.04 LTS:
linux-image-3.11.0-24-generic 3.11.0-24.41~precise1
linux-image-3.11.0-24-generic-lpae 3.11.0-24.41~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.
