Description David Lawrence 2005-03-30 23:29:36 UTC

http://secunia.com/advisories/12903/

A vulnerability has been reported in ESP Ghostscript, which can be exploited by
malicious, local users to perform certain actions on a vulnerable system with
escalated privileges.

The vulnerability is caused due to temporary files being created insecurely by
the "pj-gs.sh", "ps2epsi", "pv.sh", and "sysvlp.sh" scripts. This can be
exploited via symlink attacks to create or overwrite arbitrary files with the
privileges of the user invoking a vulnerable script.

Comment 1 David Eisenstein 2005-09-29 12:15:53 UTC

Red Hat issued RHSA-2005:081-01:
   http://rhn.redhat.com/errata/RHSA-2005-081.html
for this bug for RHEL 3.  RHEL uses ghostscript-7.05.

Our most recent ghostscript Packages:

RH7.3:    16325468 May 28  2003 ghostscript-6.52-9.5.src.rpm
RH9:      12862638 May 28  2003 ghostscript-7.05-32.1.src.rpm
FC1:      12816599 Aug 17  2004 ghostscript-7.07-15.4.src.rpm
FC2:      11920172 May 07  2004 ghostscript-7.07-25.src.rpm

This bug is mislabeled:  It should have package "ghostscript", not "gv".
This bug affects FC2 also.

Comment 2 Pekka Savola 2005-10-01 04:49:32 UTC

changed.

Comment 3 Matthew Miller 2006-10-23 19:14:40 UTC

FWIW, This appears fixed in current FC3 and FC4.

Comment 4 David Eisenstein 2007-04-12 00:25:34 UTC

Red Hat Linux and Fedora Core releases <=4 are now completely unmaintained.
These bugs can't be fixed in these versions.  If the issue still persists in
current Fedora Core releases, please reopen.  Thank you, and sorry about this.
