Ubuntu Security Notice USN-1404-1
March 27, 2012
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 11.10
The system could be made to deny services if it received specially crafted
local area network traffic.
- linux-ti-omap4: Linux kernel for OMAP4
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.
The problem can be corrected by updating your system to the following
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.
