Description Tim Sammut (RETIRED) gentoo-dev

From the Debian bug at $URL:

According to pdfroff(1) (and my inspection of the source code), pdfroff
uses $$ (the current pid) to create temporary files.  This is extremely
easy to predict, and thus, insecure.

Please fix both the code and the documentation so that they securely
generate (or reference) temporary files.


There is a patch from Owl at:
http://cvsweb.openwall.com/cgi/cvsweb.cgi/~checkout~/Owl/packages/groff/groff-1.20.1-owl-tmp.diff?rev=1.2;content-type=text%2Fplain

Does this affect latest stable? If not, latest testing?

Just compared the patch with the groff Git repo [0] and upstream still has not committed.  However, there is no substance here proving a vulnerability exists.
