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

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.
