Ubuntu 16.04 LTS : haproxy vulnerability (USN-3011-1)

Medium Nessus Plugin ID 91727


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


Falco Schmutz discovered that HAProxy incorrectly handled the reqdeny filter. A remote attacker could use this issue to cause HAProxy to crash, 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.
