Ubuntu Security Notice USN-1824-1
May 15, 2013

linux vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 10.04 LTS

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux: Linux kernel

Details:

Mathias Krause discovered an information leak in the Linux kernel's ISO
9660 CDROM file system driver. A local user could exploit this flaw to
examine some of the kernel's heap memory. (CVE-2012-6549)

Mathias Krause discovered a flaw in xfrm_user in the Linux kernel. A local
attacker with NET_ADMIN capability could potentially exploit this flaw to
escalate privileges. (CVE-2013-1826)

A buffer overflow was discovered in the Linux Kernel's USB subsystem for
devices reporting the cdc-wdm class. A specially crafted USB device when
plugged-in could cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2013-1860)

An information leak was discovered in the Linux kernel's /dev/dvb device. A
local user could exploit this flaw to obtain sensitive information from the
kernel's stack memory. (CVE-2013-1928)

An information leak in the Linux kernel's dcb netlink interface was
discovered. A local user could obtain sensitive information by examining
kernel stack memory. (CVE-2013-2634)

Update instructions:

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

Ubuntu 10.04 LTS:
linux-image-2.6.32-47-386 2.6.32-47.109
linux-image-2.6.32-47-generic 2.6.32-47.109
linux-image-2.6.32-47-generic-pae 2.6.32-47.109
linux-image-2.6.32-47-ia64 2.6.32-47.109
linux-image-2.6.32-47-lpia 2.6.32-47.109
linux-image-2.6.32-47-powerpc 2.6.32-47.109
linux-image-2.6.32-47-powerpc-smp 2.6.32-47.109
linux-image-2.6.32-47-powerpc64-smp 2.6.32-47.109
linux-image-2.6.32-47-preempt 2.6.32-47.109
linux-image-2.6.32-47-server 2.6.32-47.109
linux-image-2.6.32-47-sparc64 2.6.32-47.109
linux-image-2.6.32-47-sparc64-smp 2.6.32-47.109
linux-image-2.6.32-47-versatile 2.6.32-47.109
linux-image-2.6.32-47-virtual 2.6.32-47.109

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.
