| Description: | The remote host is missing an update to libxml2 announced via advisory USN-640-1.
A security issue affects the following Ubuntu releases:
Ubuntu 6.06 LTS Ubuntu 7.04 Ubuntu 7.10 Ubuntu 8.04 LTS
This advisory also applies to the corresponding versions of Kubuntu, Edubuntu, and Xubuntu.
Details follow:
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.
Solution: The problem can be corrected by upgrading your system to the following package versions:
Ubuntu 6.06 LTS: libxml2 2.6.24.dfsg-1ubuntu1.2
Ubuntu 7.04: libxml2 2.6.27.dfsg-1ubuntu3.2
Ubuntu 7.10: libxml2 2.6.30.dfsg-2ubuntu1.2
Ubuntu 8.04 LTS: libxml2 2.6.31.dfsg-2ubuntu1.1
In general, a standard system upgrade is sufficient to effect the necessary changes.
