Details

Dan Rosenberg reported errors in the OSS (Open Sound System) MIDI
interface. A local attacker on non-x86 systems might be able to cause a
denial of service. (CVE-2011-1476)

Dan Rosenberg reported errors in the kernel's OSS (Open Sound System)
driver for Yamaha FM synthesizer chips. A local user can exploit this to
cause memory corruption, causing a denial of service or privilege
escalation. (CVE-2011-1477)

Ben Hutchings reported a flaw in the kernel's handling of corrupt LDM
partitions. A local user could exploit this to cause a denial of service or
escalate privileges. (CVE-2011-2182)

A flaw was discovered in the Linux kernel's NFSv4 (Network File System
version 4) file system. A local, unprivileged user could use this flaw to
cause a denial of service by creating a file in a NFSv4 filesystem.
(CVE-2011-4324)

A flaw was found in how the linux kernel handles user-space held futexs. An
unprivileged user could exploit this flaw to cause a denial of service or
possibly elevate privileges. (CVE-2012-0028)

Update instructions

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

Ubuntu 8.04

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.
