RHSA-2005-049: cups Vulnerability Scan

Vulnerability Scan Summary
Check for the version of the cups packages

Detailed Explanation for this Vulnerability Test

Updated CUPS packages that fixes a security issue are now available.

The Common UNIX Printing System provides a portable printing layer for
UNIX(R) operating systems.

A buffer overflow flaw was found in the Decrypt::makeFileKey2 function of
Xpdf which also affects the CUPS pdftops filter due to a shared codebase.
A possible hacker who has the ability to send a malicious PDF file to a printer
could possibly execute arbitrary code as the "lp" user. The Common
Vulnerabilities and Exposures project ( has assigned the name
CVE-2005-0064 to this issue.

Red Hat believes that the Exec-Shield technology (enabled by default since
Update 3) will block attempts to remotely exploit these buffer overflow
vulnerabilities on x86 architectures.

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