RHSA-2004-543: cups Vulnerability Scan

Vulnerability Scan Summary
Check for the version of the cups packages

Detailed Explanation for this Vulnerability Test

Updated cups packages that fix denial of service issues, a security
information leak, as well as other various bugs are now available.

The Common UNIX Printing System (CUPS) is a print spooler.

During a source code audit, Chris Evans discovered a number of integer
overflow bugs that affect xpdf. CUPS contains a copy of the xpdf code used
for parsing PDF files and is therefore affected by these bugs. A possible hacker
who has the ability to send a malicious PDF file to a printer could cause
CUPS to crash or possibly execute arbitrary code. The Common
Vulnerabilities and Exposures project ( has assigned the name
CVE-2004-0888 to this issue.

When set up to print to a shared printer via Samba, CUPS would authenticate
with that shared printer using a username and password. By default, the
username and password used to connect to the Samba share is written
into the error log file. A local user who is able to read the error log
file could collect these usernames and passwords. The Common
Vulnerabilities and Exposures project ( has assigned the name
CVE-2004-0923 to this issue.

These updated packages also include a fix that prevents some CUPS
configuration files from being accidentally replaced.

All users of CUPS should upgrade to these updated packages, which
resolve these issues.
