18 February 2014

Several security issues were fixed in the kernel.

Packages

  • linux - Linux kernel

Details

Vasily Kulikov reported a flaw in the Linux kernel's implementation of
ptrace. An unprivileged local user could exploit this flaw to obtain
sensitive information from kernel memory. (CVE-2013-2929)

A flaw in the handling of memory regions of the kernel virtual machine
(KVM) subsystem was discovered. A local user with the ability to assign a
device could exploit this flaw to cause a denial of service (memory
consumption). (CVE-2013-4592)

Nico Golde and Fabian Yamaguchi reported a flaw in the Linux kernel's
debugfs filesystem. An administrative local user could exploit this flaw to
cause a denial of service (OOPS). (CVE-2013-6378)

Nico Golde and Fabian Yamaguchi reported a flaw in the driver for Adaptec
AACRAID scsi raid devices in the Linux kernel. A local user could use this
flaw to cause a denial of service or possibly other unspecified impact.
(CVE-2013-6380)

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 12.10

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.
