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.
