USN-1412-1: Linux kernel vulnerability

Releases

• Ubuntu 11.10

Packages

• linux - Linux kernel

Details

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-powerpc-smp - 3.0.0-17.30
• linux-image-3.0.0-17-generic - 3.0.0-17.30
• linux-image-3.0.0-17-virtual - 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-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-powerpc - 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.
