Package        : groff
Problem type   : printf format attack
Debian-specific: no

Zenith Parse found a security problem in groff (the GNU version of
troff). The pic command was vulnerable to a printf format attack
which made it possible to circumvent the -S option and execute
arbitrary code.

This has been fixed in version 1.15.2-2.
