Synopsis

The remote Red Hat host is missing a security update for nss-pam-ldapd.

Description

The remote Redhat Enterprise Linux 6 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2013:0590 advisory.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL nss-pam-ldapd package based on the guidance in RHSA-2013:0590.
