Ubuntu 12.04 LTS / 14.04 LTS / 16.04 LTS / 16.10 : libevent vulnerabilities (USN-3228-1)

High Nessus Plugin ID 97721


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


Guido Vranken discovered that libevent incorrectly handled memory when processing certain data. 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-2.0-5 package.
