Vulnerability from csaf_redhat - Published: 2002-06-04 19:38 - Updated: 2024-11-21 22:21
Summary
Red Hat Security Advisory: : Ghostscript command execution vulnerability

Notes

Topic
Updated packages are available for GNU Ghostscript which fix a vulnerability found during Postscript interpretation.
Details
Ghostscript is a program for displaying PostScript files or printing them to non-PostScript printers. An untrusted PostScript file can cause ghostscript to execute arbitrary commands due to insufficient checking. Since ghostscript is often used during the course of printing a document (and is run as user 'lp'), all users should install these fixed packages. The problem is fixed in the 6.53 source release of GNU Ghostscript, and the fix has been backported and applied to the packages referenced by this advisory. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2002-0363 to this issue. Please note that this vulnerability is different to the 'local file read' issue corrected by our previous Ghostscript errata (RHSA-2001:112 and RHSA-2001:138)
