Published: 2013-01-21 04:08:00
CVE Author: NIST National Vulnerability Database

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

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

Affected Versions:
autofs on CentOS 5

Recommendations:
Please install the updated Linux Distribution Packages.

Technical Details:
The autofs utility controls the operation of the automount daemon. The automount daemon automatically mounts and unmounts file systems. A bug fix included in RHBA-2012:0264 introduced a denial of service flaw in autofs. When using autofs with LDAP, a local user could use this flaw to crash autofs, preventing future mount requests from being processed until the autofs service was restarted. Note: This flaw did not impact existing mounts (except for preventing mount expiration). (CVE-2012-2697) Red Hat would like to thank Ray Rocker for reporting this issue. This update also fixes the following bugs: * The autofs init script sometimes timed out waiting for the automount daemon to exit and returned a shutdown failure if the daemon failed to exit in time. To resolve this problem, the amount of time that the init script waits for the daemon has been increased to allow for cases where servers are slow to respond or there are many active mounts. (BZ#585058) * Due to an omission when backporting a change, autofs attempted to download the entire LDAP map at startup. This mistake has now been corrected. (BZ#767428) * A function to check the validity of a mount location was meant to check only for a small subset of map location errors. A recent modification in error reporting inverted a logic test in this validating function. Consequently, the scope of the test was widened, which caused the automount daemon to report false positive failures. With this update, the faulty logic test has been corrected and false positive failures no longer occur. (BZ#798448) * When there were many attempts to access invalid or non-existent keys, the automount daemon used excessive CPU resources. As a consequence, systems sometimes became unresponsive. The code has been improved so that automount checks for invalid keys earlier in the process which has eliminated a significant amount of the processing overhead. (BZ#847101) * The auto.master(5) man page did not document the 't, --timeout' option in the FORMAT options section. This update adds this information to the man page. (BZ#859890) This update also adds the following enhancement: * Previously, it was not possible to configure separate timeout values for individual direct map entries in the autofs master map. This update adds this functionality. (BZ#690404) All users of autofs are advised to upgrade to this updated Linux Distribution Package, which contains backported patches to correct these issues and add this enhancement.

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".
