CVE-2009-5082
First published: Thu Jun 30 2011(Updated: )
The (1) configure and (2) config.guess scripts in GNU troff (aka groff) 1.20.1 on Openwall GNU/*/Linux (aka Owl) improperly create temporary files upon a failure of the mktemp function, which makes it easier for local users to overwrite arbitrary files via a symlink attack on a temporary file.
