                Mandrake Linux Security Update Advisory
________________________________________________________________________

Package name:           groff
Advisory ID:            MDKSA-2002:012
Date:                   February 7th, 2002
Affected versions:      7.2, 8.0, 8.1, Single Network Firewall 7.2
________________________________________________________________________

Problem Description:

 zen-parse discovered an exploitable buffer overflow in groff's
 preprocessor.  If groff is invoked using the LPRng printing system, an
 attacker can gain rights as the "lp" user.  Likewise, this may be
 remotely exploitable if lpd is running and remotely accessible and the
 attacker knows the name of the printer and it's spool file.
