Ubuntu 11.04: USN-1167-1 Moderate: Multiple Kernel Flaws

ubuntu
Calendar Grey July 13, 2011
Scroller Ubuntu
Ensure your Ubuntu installation is current by applying updates addressing various kernel vulnerabilities to safeguard against possible attacks.
Multiple kernel flaws have been fixed.

Summary

Multiple kernel flaws have been fixed.

Software Description:

- linux: Linux kernel

Details:

Dan Rosenberg discovered that the Linux kernel TIPC implementation

contained multiple integer signedness errors. A local attacker could

exploit this to gain root privileges. (CVE-2010-3859)

Dan Rosenberg discovered that the CAN protocol on 64bit systems did not

correctly calculate the size of certain buffers. A local attacker could

exploit this to crash the system or possibly execute arbitrary code as the

root user. (CVE-2010-3874)

Vasiliy Kulikov discovered that the Linux kernel X.25 implementation did

not correctly clear kernel memory. A local attacker could exploit this to

read kernel stack memory, leading to a loss of privacy. (CVE-2010-3875)

Vasiliy Kulikov discovered that the Linux kernel sockets implementation did

not properly initialize certain structures. A local attacker could exploit

this to read kernel stack memory, leading to a loss of privacy.

Update Instructions

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

Ubuntu 11.04:
  linux-image-2.6.38-10-generic   2.6.38-10.46
  linux-image-2.6.38-10-generic-pae  2.6.38-10.46
  linux-image-2.6.38-10-omap      2.6.38-10.46
  linux-image-2.6.38-10-powerpc   2.6.38-10.46
  linux-image-2.6.38-10-powerpc-smp  2.6.38-10.46
  linux-image-2.6.38-10-powerpc64-smp  2.6.38-10.46
  linux-image-2.6.38-10-server    2.6.38-10.46
  linux-image-2.6.38-10-versatile  2.6.38-10.46
  linux-image-2.6.38-10-virtual   2.6.38-10.46

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.
