    CVE-2009-5081

    Published: 30 Jun 2011Last Modified: 10 Apr 2026

    Summary:

    Details: The (1) config.guess, (2) contrib/groffer/perl/groffer.pl, and (3) contrib/groffer/perl/roff2.pl scripts in GNU troff (aka groff) 1.21 and earlier use an insufficient number of X characters in the template argument to the tempfile function, which makes it easier for local users to overwrite arbitrary files via a symlink attack on a temporary file, a different vulnerability than CVE-2004-0969.
