CentOS Update for device-mapper-multipath CESA-2009:0411 centos4 i386

Published: 2011-08-09 06:20:34
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:

The remote host is missing an update for the 'device-mapper-multipath' Linux Distribution Package(s) announced via the referenced advisory.

Affected Versions:
device-mapper-multipath on CentOS 4

Technical Details:
The device-mapper multipath Linux Distribution Packages provide tools to manage multipath devices by issuing instructions to the device-mapper multipath kernel module, and by managing the creation and removal of partitions for device-mapper devices. It was discovered that the multipathd daemon set incorrect permissions on the socket used to communicate with command line clients. An unprivileged, local user could use this flaw to send commands to multipathd, resulting in access disruptions to storage devices accessible via multiple paths and, possibly, file system corruption on these devices. (CVE-2009-0115) Users of device-mapper-multipath are advised to upgrade to these updated Linux Distribution Packages, which contain a backported patch to resolve this issue. The multipathd service must be restarted for the changes to take effect. Important: the version of the multipathd daemon in Red Hat Enterprise Linux 5 has a known issue which may cause a machine to become unresponsive when the multipathd service is stopped. This issue is tracked in the Bugzilla bug #494582. A link is provided in the References section of this erratum. Until this issue is resolved, we recommend restarting the multipathd service by issuing the following commands in sequence: # killall -KILL multipathd # service multipathd restart

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".
