Details

It was discovered that libxml2 had a heap-based buffer underflow
when parsing entities. If a user or automated system were tricked into
processing a specially crafted XML document, applications linked against
libxml2 could be made to crash or possibly execute arbitrary code.

Update instructions

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

Ubuntu 8.04
Ubuntu 12.10
Ubuntu 12.04
Ubuntu 11.10
Ubuntu 10.04

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