USN-569-1: libxml2 vulnerability

Releases

• Ubuntu 7.10
• Ubuntu 7.04
• Ubuntu 6.10
• Ubuntu 6.06

Packages

• libxml2 -

Details

Brad Fitzpatrick discovered that libxml2 did not correctly handle certain
UTF-8 sequences. If a remote attacker were able to trick a user or
automated system into processing a specially crafted XML document, the
application linked against libxml2 could enter an infinite loop, leading
to a denial of service via CPU resource consumption.

Update instructions

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

Ubuntu 7.10

• libxml2 - 2.6.30.dfsg-2ubuntu1.1

Ubuntu 7.04

• libxml2 - 2.6.27.dfsg-1ubuntu3.1

Ubuntu 6.10

• libxml2 - 2.6.26.dfsg-2ubuntu4.1

Ubuntu 6.06

• libxml2 - 2.6.24.dfsg-1ubuntu1.1

After a standard system upgrade you need to restart your session to effect
the necessary changes.
