CONECTIVA LINUX SECURITY ANNOUNCEMENT
- --------------------------------------------------------------------------
PACKAGE : groff
SUMMARY : Multiple vulnerabilities in groff
DATE : 2001-10-02 16:36:00
ID : CLA-2001:428
RELEVANT
RELEASES : 4.0, 4.0es, 4.1, 4.2, 5.0, prg graficos, ecommerce, 5.1, 6.0
- -------------------------------------------------------------------------
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.
