Ubuntu 10.04 LTS / 12.04 LTS / 14.04 LTS / 14.10 : libevent vulnerability (USN-2477-1)

High Nessus Plugin ID 80852


The remote Ubuntu host is missing one or more security-related patches.


Andrew Bartlett discovered that libevent incorrectly handled large inputs to the evbuffer API. A remote attacker could possibly use this issue with an application that uses libevent to cause a denial of service, or possibly execute arbitrary code.

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 libevent-1.4-2 and / or libevent-2.0-5 packages.
