The Common UNIX Printing System (CUPS) provides a portable printing layer for UNIX operating systems.
An invalid free flaw was found in the way the CUPS server parsed Internet Printing Protocol (IPP) packets. A malicious user able to send IPP requests to the CUPS server could use this flaw to crash the CUPS server. (CVE-2010-2941)
Red Hat would like to thank Emmanuel Bouillon of NATO C3 Agency for reporting this issue.
