Ubuntu Security Notice USN-1344-1
January 24, 2012

linux vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 10.04 LTS


Several security issues were fixed in the kernel.

Software Description:
- linux: Linux kernel


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.

Update instructions:

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

Ubuntu 10.04 LTS:
  linux-image-2.6.32-38-386       2.6.32-38.83
  linux-image-2.6.32-38-generic   2.6.32-38.83
  linux-image-2.6.32-38-generic-pae  2.6.32-38.83
  linux-image-2.6.32-38-ia64      2.6.32-38.83
  linux-image-2.6.32-38-lpia      2.6.32-38.83
  linux-image-2.6.32-38-powerpc   2.6.32-38.83
  linux-image-2.6.32-38-powerpc-smp  2.6.32-38.83
  linux-image-2.6.32-38-powerpc64-smp  2.6.32-38.83
  linux-image-2.6.32-38-preempt   2.6.32-38.83
  linux-image-2.6.32-38-server    2.6.32-38.83
  linux-image-2.6.32-38-sparc64   2.6.32-38.83
  linux-image-2.6.32-38-sparc64-smp  2.6.32-38.83
  linux-image-2.6.32-38-versatile  2.6.32-38.83
  linux-image-2.6.32-38-virtual   2.6.32-38.83

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.

  CVE-2011-2203, CVE-2011-4110
