RHEL 4 : krb5 (RHSA-2005:045)

critical Nessus Plugin ID 17173

Synopsis

The remote Red Hat host is missing a security update for krb5.

Description

The remote Redhat Enterprise Linux 4 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2005:045 advisory.

Kerberos is a networked authentication system that uses a trusted third party (a KDC) to authenticate clients and servers to each other.

A heap based buffer overflow bug was found in the administration library of Kerberos 1.3.5 and earlier. This bug could allow an authenticated remote attacker to execute arbitrary commands on a realm's master Kerberos KDC.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-1189 to this issue.

All users of krb5 should upgrade to these updated packages, which contain backported security patches to resolve these issues.

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 krb5 package based on the guidance in RHSA-2005:045.
