USN-2338-1: Lua vulnerability

3 September 2014

Lua could be made to crash or run programs.



  • lua5.1 - Simple, extensible, embeddable programming language


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.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 14.04
Ubuntu 12.04

In general, a standard system update will make all the necessary changes.
