USN-1328-1: Linux kernel (Marvell DOVE) vulnerabilities

Releases

• Ubuntu 10.10

Packages

• linux-mvl-dove - Linux kernel for DOVE

Details

Clement Lecigne discovered a bug in the HFS filesystem. A local attacker
could exploit this to cause a kernel oops. (CVE-2011-2203)

A flaw was found in how the Linux kernel handles user-defined key types. An
unprivileged local user could exploit this to crash the system.
(CVE-2011-4110)

Update instructions

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

Ubuntu 10.10

• linux-image-2.6.32-422-dove - 2.6.32-422.40

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.
