The remote host is missing an update to apr-util announced via advisory USN-813-3.

The problem can be corrected by upgrading your system to the following package versions: Ubuntu 8.04 LTS: libaprutil1 1.2.12+dfsg-3ubuntu0.2 Ubuntu 8.10: libaprutil1 1.2.12+dfsg-7ubuntu0.3 Ubuntu 9.04: libaprutil1 1.2.12+dfsg-8ubuntu0.3 After a standard system upgrade you need to restart any applications using apr-util, such as Subversion and Apache, to effect the necessary changes. https://secure1.securityspace.com/smysecure/catid.html?in=USN-813-3

USN-813-1 fixed vulnerabilities in apr. This update provides the corresponding updates for apr-util. 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.
