RHEL 4 : cups (RHSA-2009:1083)

high Nessus Plugin ID 39307

Synopsis

The remote Red Hat host is missing one or more security updates for cups.

Description

The remote Redhat Enterprise Linux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2009:1083 advisory.

The Common UNIX Printing System (CUPS) provides a portable printing layer for UNIX operating systems. The Internet Printing Protocol (IPP) allows users to print and manage printing-related tasks over a network. The CUPS pdftops filter converts Portable Document Format (PDF) files to PostScript. pdftops is based on Xpdf and the CUPS imaging library.

A NULL pointer dereference flaw was found in the CUPS IPP routine, used for processing incoming IPP requests for the CUPS scheduler. An attacker could use this flaw to send specially-crafted IPP requests that would crash the cupsd daemon. (CVE-2009-0949)

A use-after-free flaw was found in the CUPS scheduler directory services routine, used to process data about available printers and printer classes.
An attacker could use this flaw to cause a denial of service (cupsd daemon stop or crash). (CVE-2009-1196)

Multiple integer overflows flaws, leading to heap-based buffer overflows, were found in the CUPS pdftops filter. An attacker could create a malicious PDF file that would cause pdftops to crash or, potentially, execute arbitrary code as the lp user if the file was printed.
(CVE-2009-0791)

Red Hat would like to thank Anibal Sacco from Core Security Technologies for reporting the CVE-2009-0949 flaw, and Swen van Brussel for reporting the CVE-2009-1196 flaw.

Users of cups are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing this update, the cupsd daemon will be restarted automatically.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL cups package based on the guidance in RHSA-2009:1083.
