The Common UNIX Printing System (CUPS) provides a portable printing layerfor UNIX(R) operating systems. The Internet Printing Protocol (IPP) is astandard network protocol for remote printing, as well as managing printjobs.A flaw was found in the way CUPS handles the addition and removal of remoteshared printers via IPP. A remote attacker could send malicious UDP IPPpackets causing the CUPS daemon to crash. (CVE-2008-0882)Note: the default configuration of CUPS on Red Hat Enterprise Linux 5 willonly accept requests of this type from the local subnet. This issue did notaffect the versions of CUPS as shipped with Red Hat Enterprise Linux 3 or4.All cups users are advised to upgrade to these updated packages, whichcontain a backported patch to resolve this issue.
