The remote host is missing updates announced in
advisory RHSA-2008:0161.
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.
Solution:
Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
