RHEL 3 : cups (RHSA-2004:543)

critical Nessus Plugin ID 15630


The remote Red Hat host is missing one or more security updates.


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. An attacker 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 (cve.mitre.org) 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 (cve.mitre.org) 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.


Update the affected cups, cups-devel and / or cups-libs packages.
