==========================================================================
Ubuntu Security Notice USN-1447-1
May 21, 2012

libxml2 vulnerability
==========================================================================

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

- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.04 LTS
- Ubuntu 8.04 LTS

Summary:

Applications using libxml2 could be made to crash or run programs as your
login if they opened a specially crafted file.

Software Description:
- libxml2: GNOME XML library

Details:

Juri Aedla discovered that libxml2 contained an off by one error in its
XPointer functionality. If a user or application linked against libxml2
were tricked into opening a specially crafted XML file, an attacker could
cause the application to crash or possibly execute arbitrary code with the
privileges of the user invoking the program.

Update instructions:

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

Ubuntu 12.04 LTS:
  libxml2                         2.7.8.dfsg-5.1ubuntu4.1

Ubuntu 11.10:
  libxml2                         2.7.8.dfsg-4ubuntu0.3

Ubuntu 11.04:
  libxml2                         2.7.8.dfsg-2ubuntu0.4

Ubuntu 10.04 LTS:
  libxml2                         2.7.6.dfsg-1ubuntu1.5

Ubuntu 8.04 LTS:
  libxml2                         2.6.31.dfsg-2ubuntu1.9

After a standard system update you need to reboot your computer to make
all the necessary changes.
