A vulnerability was found in GNU groff up to 1.21. It has been rated as problematic. Affected by this issue is the function tempfile
. The manipulation of the argument template
with an unknown input leads to a link following vulnerability. Using CWE to declare the problem leads to CWE-59. The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource. Impacted is integrity, and availability. CVE summarizes:
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.
The weakness was released 06/30/2011 (oss-sec). The advisory is available at openwall.com. This vulnerability is handled as CVE-2009-5081 since 06/30/2011.
