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, and we recommend that you upgrade your groff packages immediately.

Fixed in:
