Red Hat Security Advisory

 

Synopsis: Important: nss-pam-ldapd security update

Advisory ID: RHSA-2013:0590-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2013-0590.html

Issue date: 2013-03-04

CVE Names: CVE-2013-0288

=====================================================================

 

1. Summary:

 

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.

 

2. Relevant releases/architectures:

 

Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64

Red Hat Enterprise Linux HPC Node (v. 6) - x86_64

Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64

Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64

 

3. 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.

 

4. Solution:
