CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:M/Au:N/C:P/I:P/A:P

Summary:
The remote host is missing an update for the 'cups' Linux Distribution Package(s) announced via the referenced advisory.

Affected Versions:
cups on CentOS 3

Technical Details:
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 Linux Distribution Packages, which contain backported patches to correct these issues. After installing this update, the cupsd daemon will be restarted automatically.

Recommendations:
Please install the updated Linux Distribution Packages.

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
