Ubuntu 12.04 LTS / 14.04 LTS : lua5.1 vulnerability (USN-2338-1)

Medium Nessus Plugin ID 77525


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


It was discovered that Lua incorrectly handled certain vararg functions with a large number of fixed parameters. An attacker could use this issue to cause Lua applications to crash, resulting in 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 liblua5.1-0 and / or lua5.1 packages.
