Ubuntu Security Notice USN-2111-1
February 18, 2014
linux-lts-quantal 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-quantal: Linux hardware enablement kernel from Quantal
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 12.04 LTS:
linux-image-3.5.0-46-generic 3.5.0-46.70~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.
