Published: 2012-07-30 12:07:38
CVE Author: NIST National Vulnerability Database

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

Summary:
The remote host is missing an update for the 'xorg-x11-server-utils' Linux Distribution Package(s) announced via the referenced advisory.

Affected Versions:
xorg-x11-server-utils on CentOS 5

Recommendations:
Please install the updated Linux Distribution Packages.

Technical Details:
The xorg-x11-server-utils Linux Distribution Package contains a collection of utilities used to modify and query the runtime configuration of the X.Org server. X.Org is an open source implementation of the X Window System. A flaw was found in the X.Org X server resource database utility, xrdb. Certain variables were not properly sanitized during the launch of a user's graphical session, which could possibly allow a remote attacker to execute arbitrary code with root privileges, if they were able to make the display manager execute xrdb with a specially-crafted X client hostname. For example, by configuring the hostname on the target system via a crafted DHCP reply, or by using the X Display Manager Control Protocol (XDMCP) to connect to that system from a host that has a special DNS name. (CVE-2011-0465) Red Hat would like to thank Matthieu Herrb for reporting this issue. Upstream acknowledges Sebastian Krahmer of the SuSE Security Team as the original reporter. Users of xorg-x11-server-utils should upgrade to this updated Linux Distribution Package, which contains a backported patch to resolve this issue. All running X.Org server instances must be restarted for this update to take effect.

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".
