Description

USN-813-1 fixed vulnerabilities in apr. This update provides the corresponding updates for apr as provided by Apache on Ubuntu 6.06 LTS.

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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
