Ubuntu 12.04 LTS / 12.10 / 13.04 : haproxy vulnerability (USN-1889-1)

Medium Nessus Plugin ID 66962


The remote Ubuntu host is missing a security-related patch.


David Torgerson discovered that HAProxy incorrectly parsed certain HTTP headers. A remote attacker could use this issue to cause HAProxy to stop responding, resulting in a denial of service.

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.


Update the affected haproxy package.
