USN-2264-1: Linux kernel vulnerabilities

Releases

• Ubuntu 13.10

Packages

• linux - Linux kernel

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 13.10

• linux-image-3.11.0-24-generic-lpae - 3.11.0-24.41
• linux-image-3.11.0-24-generic - 3.11.0-24.41

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.
