RHSA-2005:081 - Security Advisory

Synopsis

ghostscript security update

Type/Severity

Security Advisory: Low

Topic

Updated ghostscript packages that fix a PDF output issue and a temporary
file security bug are now available.

This update has been rated as having low security impact by the Red Hat
Security Response Team.

Description

Ghostscript is a program for displaying PostScript files or printing them
to non-PostScript printers.

A bug was found in the way several of Ghostscript's utility scripts created
temporary files. A local user could cause these utilities to overwrite
files that the victim running the utility has write access to. The Common
Vulnerabilities and Exposures project assigned the name CAN-2004-0967 to
this issue.

Additionally, this update addresses the following issue:

A problem has been identified in the PDF output driver, which can cause
output to be delayed indefinitely on some systems. The fix has been
backported from GhostScript 7.07.

All users of ghostscript should upgrade to these updated packages, which
contain backported patches to resolve these issues.
