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:

A flaw was discovered in the Linux kernel's compat ioctls for Adaptec
AACRAID scsi raid devices. An unprivileged local user could send
administrative commands to these devices potentially compromising the data
stored on the device. (CVE-2013-6383)

mpd reported an information leak in the recvfrom, recvmmsg, and recvmsg
system calls in the Linux kernel. An unprivileged local user could exploit
this flaw to obtain sensitive information from kernel stack memory.
(CVE-2013-7263)

mpb reported an information leak in the Layer Two Tunneling Protocol (l2tp)
of the Linux kernel. A local user could exploit this flaw to obtain
sensitive information from kernel stack memory. (CVE-2013-7264)

mpb reported an information leak in the Phone Network protocol (phonet) in
the Linux kernel. A local user could exploit this flaw to obtain sensitive
information from kernel stack memory. (CVE-2013-7265)

mpb reported an information leak in the Low-Rate Wireless Personal Area
Networks support (IEEE 802.15.4) in the Linux kernel. A local user could
exploit this flaw to obtain sensitive information from kernel stack memory.
(CVE-2013-7281)

Update instructions:

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

Ubuntu 10.04 LTS:
  linux-image-2.6.32-56-386       2.6.32-56.118
  linux-image-2.6.32-56-generic   2.6.32-56.118
  linux-image-2.6.32-56-generic-pae  2.6.32-56.118
  linux-image-2.6.32-56-ia64      2.6.32-56.118
  linux-image-2.6.32-56-lpia      2.6.32-56.118
  linux-image-2.6.32-56-powerpc   2.6.32-56.118
  linux-image-2.6.32-56-powerpc-smp  2.6.32-56.118
  linux-image-2.6.32-56-powerpc64-smp  2.6.32-56.118
  linux-image-2.6.32-56-preempt   2.6.32-56.118
  linux-image-2.6.32-56-server    2.6.32-56.118
  linux-image-2.6.32-56-sparc64   2.6.32-56.118
  linux-image-2.6.32-56-sparc64-smp  2.6.32-56.118
  linux-image-2.6.32-56-versatile  2.6.32-56.118
  linux-image-2.6.32-56-virtual   2.6.32-56.118

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.
