What is CVE-2009-5081?

The GNU troff product, including versions up to 1.21, contains a vulnerability in the scripts config.guess, contrib/groffer/perl/groffer.pl, and contrib/groffer/perl/roff2.pl, using an inadequate number of X characters in the template argument for the tempfile function. This flaw can allow local users to overwrite arbitrary files through a symlink attack via a temporary file, thus posing a significant security risk.
