RHEL 2.1 / 3 / 4 : krb5 (RHSA-2005:330)

High Nessus Plugin ID 17659


The remote Red Hat host is missing one or more security updates.


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.


Update the affected packages.
