USN-640-1: libxml2 vulnerability

Releases

• Ubuntu 8.04
• Ubuntu 7.10
• Ubuntu 7.04
• Ubuntu 6.06

Packages

• 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

• libxml2 - 2.6.31.dfsg-2ubuntu1.1

Ubuntu 7.10

• libxml2 - 2.6.30.dfsg-2ubuntu1.2

Ubuntu 7.04

• libxml2 - 2.6.27.dfsg-1ubuntu3.2

Ubuntu 6.06

• libxml2 - 2.6.24.dfsg-1ubuntu1.2

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