"Updated cups packages that fix two security issues are now available
for Red Hat Enterprise Linux 4.

This update has been rated as having important security impact by the
Red Hat Security Response Team.

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

A flaw was found in the way CUPS handled the addition and removal of
remote shared printers via IPP. A remote attacker could send malicious
UDP IPP packets causing the CUPS daemon to attempt to dereference
already freed memory and crash. (CVE-2008-0597)

A memory management flaw was found in the way CUPS handled the
addition and removal of remote shared printers via IPP. When shared
printer was removed, allocated memory was not properly freed, leading
to a memory leak possibly causing CUPS daemon crash after exhausting
available memory. (CVE-2008-0596)

These issues were found during the investigation of CVE-2008-0882,
which did not affect Red Hat Enterprise Linux 4.

Note that the default configuration of CUPS on Red Hat Enterprise
Linux 4 allow requests of this type only from the local subnet.

All CUPS users are advised to upgrade to these updated packages, which
contain backported patches to resolve these issues."
