CentOS 3 : krb5 (CESA-2005:330)

high Nessus Plugin ID 21803

Synopsis

The remote CentOS host is missing one or more security updates.

Description

Updated krb5 packages which fix two buffer overflow vulnerabilities in the included Kerberos-aware telnet client are now available.

This update has been rated as having important security impact by the Red Hat Security Response Team.

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

The krb5-workstation package includes a Kerberos-aware telnet client.
Two buffer overflow flaws were discovered in the way the telnet client handles messages from a server. An attacker may be able to execute arbitrary code on a victim's machine if the victim can be tricked into connecting to a malicious telnet server. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2005-0468 and CVE-2005-0469 to these issues.

Users of krb5 should update to these erratum packages which contain a backported patch to correct this issue.

Red Hat would like to thank iDEFENSE for their responsible disclosure of this issue.

Solution

Update the affected krb5 packages.
