libxml2 vulnerability

  • libxml2 -

Details

Andreas Solberg discovered that libxml2 did not handle recursive entities
safely. If an application linked against libxml2 were made to process
a specially crafted XML document, a remote attacker could exhaust the
system's CPU resources, leading to a denial of service.

Update instructions

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

Ubuntu 8.04
Ubuntu 7.10
Ubuntu 7.04
Ubuntu 6.06

In general, a standard system upgrade is sufficient to effect the
necessary changes.
