Oracle Linux 5 : cups (ELSA-2008-0192)
Critical Nessus Plugin ID 67670
SynopsisThe remote Oracle Linux host is missing one or more security updates.
DescriptionFrom Red Hat Security Advisory 2008:0192 :
Updated cups packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5.
This update has been rated as having moderate 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 heap buffer overflow flaw was found in a CUPS administration interface CGI script. A local attacker able to connect to the IPP port (TCP port 631) could send a malicious request causing the script to crash or, potentially, execute arbitrary code as the 'lp' user. Please note: the default CUPS configuration in Red Hat Enterprise Linux 5 does not allow remote connections to the IPP TCP port. (CVE-2008-0047)
Red Hat would like to thank 'regenrecht' for reporting this issue.
This issue did not affect the versions of CUPS as shipped with Red Hat Enterprise Linux 3 or 4.
Two overflows were discovered in the HP-GL/2-to-PostScript filter. An attacker could create a malicious HP-GL/2 file that could possibly execute arbitrary code as the 'lp' user if the file is printed.
A buffer overflow flaw was discovered in the GIF decoding routines used by CUPS image converting filters 'imagetops' and 'imagetoraster'.
An attacker could create a malicious GIF file that could possibly execute arbitrary code as the 'lp' user if the file was printed.
All cups users are advised to upgrade to these updated packages, which contain backported patches to resolve these issues.
SolutionUpdate the affected cups packages.
