Ubuntu Security Notice USN-1912-1
Posted Jul 30, 2013
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 1912-1 - Jonathan Salwan discovered an information leak in the Linux kernel's cdrom driver. A local user can exploit this leak to obtain sensitive information from kernel memory if the CD-ROM drive is malfunctioning. A flaw was discovered in the Linux kernel when an IPv6 socket is used to connect to an IPv4 destination. An unprivileged local user could exploit this flaw to cause a denial of service (system crash). An information leak was discovered in the IPSec key_socket implementation in the Linux kernel. An local user could exploit this flaw to examine potentially sensitive information in kernel memory. Various other issues were also addressed.

============================================================================

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:

Jonathan Salwan discovered an information leak in the Linux kernel's cdrom
driver. A local user can exploit this leak to obtain sensitive information
from kernel memory if the CD-ROM drive is malfunctioning. (CVE-2013-2164)

A flaw was discovered in the Linux kernel when an IPv6 socket is used to
connect to an IPv4 destination. An unprivileged local user could exploit
this flaw to cause a denial of service (system crash). (CVE-2013-2232)

An information leak was discovered in the IPSec key_socket implementation
in the Linux kernel. An local user could exploit this flaw to examine
potentially sensitive information in kernel memory. (CVE-2013-2234)

An information leak was discovered in the Linux kernel's IPSec key_socket
when using the notify_policy interface. A local user could exploit this
flaw to examine potentially sensitive information in kernel memory.
(CVE-2013-2237)

Kees Cook discovered a format string vulnerability in the Linux kernel's
disk block layer. A local user with administrator privileges could exploit
this flaw to gain kernel privileges. (CVE-2013-2851)

Update instructions:

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

Ubuntu 10.04 LTS:
linux-image-2.6.32-50-386 2.6.32-50.112
linux-image-2.6.32-50-generic 2.6.32-50.112
linux-image-2.6.32-50-generic-pae 2.6.32-50.112
linux-image-2.6.32-50-ia64 2.6.32-50.112
linux-image-2.6.32-50-lpia 2.6.32-50.112
linux-image-2.6.32-50-powerpc 2.6.32-50.112
linux-image-2.6.32-50-powerpc-smp 2.6.32-50.112
linux-image-2.6.32-50-powerpc64-smp 2.6.32-50.112
linux-image-2.6.32-50-preempt 2.6.32-50.112
linux-image-2.6.32-50-server 2.6.32-50.112
linux-image-2.6.32-50-sparc64 2.6.32-50.112
linux-image-2.6.32-50-sparc64-smp 2.6.32-50.112
linux-image-2.6.32-50-versatile 2.6.32-50.112
linux-image-2.6.32-50-virtual 2.6.32-50.112

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.
