Bug Description
Binary package hint: feynmf
References:
http://
Quoting:
"Kevin B. McCarty discovered that the feynmf.pl script creates a temporary "properly list" file at the location "$TMPDIR/
[...]
A local attacker could create symbolic links in the directory where the temporary files are written, pointing to a valid file somewhere on the filesystem that is writable by the user running Feynmf. When Feynmf writes the temporary file, the target valid file would then be overwritten with the contents of the Feynmf temporary file."

As it turns out, this is fixed in a different manner (calling /bin/tempfile) in all releases.
