RHSA-2013:0590 - Important: nss-pam-ldapd security update

Synopsis

Important: nss-pam-ldapd security update

Type/Severity

Security Advisory Important

Topic

Updated nss-pam-ldapd packages that fix one security issue are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

Description

The nss-pam-ldapd packages provide the nss-pam-ldapd daemon (nslcd), which uses a directory server to lookup name service information on behalf of a lightweight nsswitch module.

An array index error, leading to a stack-based buffer overflow flaw, was found in the way nss-pam-ldapd managed open file descriptors. An attacker able to make a process have a large number of open file descriptors and perform name lookups could use this flaw to cause the process to crash or, potentially, execute arbitrary code with the privileges of the user running the process. (CVE-2013-0288)

Red Hat would like to thank Garth Mollett for reporting this issue.

All users of nss-pam-ldapd are advised to upgrade to these updated packages, which contain a backported patch to fix this issue.
