Oracle Linux 4 : cups (ELSA-2008-0161)
Medium Nessus Plugin ID 67663
SynopsisThe remote Oracle Linux host is missing one or more security updates.
DescriptionFrom Red Hat Security Advisory 2008:0161 :
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.
SolutionUpdate the affected cups packages.
