DESCRIPTION
 Groff is the GNU version of troff, a document processor that ships 
 with most Unix systems. Among other functions, it formats system
 manual pages into human-readable form.
 
 This release fixes two security problems:
 
 1. ISS X-Force released an advisory[1] about GNU Groff utilities
 reading untrusted commands from the current working directory.
 Unsuspecting users, including root, could be tricked into running
 arbitrary commands on the system.
 
 2. Zenith Parse discovered[2] that the pic command (which is used by
 the printer daemon and others) is vulnerable to a format string
 attack which makes it possible to circumvent groff's safe mode and
 execute commands which would otherwise be disabled.


SOLUTION
 All users should upgrade.
