The remote host is missing an update to apache2 announced via advisory USN-813-2.

The problem can be corrected by upgrading your system to the following package versions: Ubuntu 6.06 LTS: libapr0 2.0.55-4ubuntu2.7 After a standard system upgrade you need to restart any applications using apr, such as Subversion and Apache, to effect the necessary changes. https://secure1.securityspace.com/smysecure/catid.html?in=USN-813-2

USN-813-1 fixed vulnerabilities in apr. This update provides the corresponding updates for apr as provided by Apache on Ubuntu 6.06 LTS. Original advisory details: Matt Lewis discovered that apr did not properly sanitize its input when allocating memory. If an application using apr processed crafted input, a remote attacker could cause a denial of service or potentially execute arbitrary code as the user invoking the application.
