Ubuntu Security Notice USN-1412-1
March 29, 2012

linux vulnerability

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

- Ubuntu 11.10


Several security issues were fixed in the kernel.

Software Description:
- linux: Linux kernel


Somnath Kotur discovered an error in the Linux kernel's VLAN (virtual lan)
and be2net drivers. An attacker on the local network could exploit this
flaw to cause a denial of service.

Update instructions:

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

Ubuntu 11.10:
  linux-image-3.0.0-17-generic    3.0.0-17.30
  linux-image-3.0.0-17-generic-pae  3.0.0-17.30
  linux-image-3.0.0-17-omap       3.0.0-17.30
  linux-image-3.0.0-17-powerpc    3.0.0-17.30
  linux-image-3.0.0-17-powerpc-smp  3.0.0-17.30
  linux-image-3.0.0-17-powerpc64-smp  3.0.0-17.30
  linux-image-3.0.0-17-server     3.0.0-17.30
  linux-image-3.0.0-17-virtual    3.0.0-17.30

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.
