Ubuntu Security Notice 4226-1 - Michael Hanselmann discovered that the CIFS implementation in the Linux kernel did not sanitize paths returned by an SMB server. An attacker controlling an SMB server could use this to overwrite arbitrary files. It was discovered that a heap-based buffer overflow existed in the Marvell WiFi-Ex Driver for the Linux kernel. A physically proximate attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.

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.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
