RHSA-2005-330: krb

Vulnerability Assessment Summary
Check for the version of the krb packages

Detailed Explanation for this Vulnerability Assessment

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. A possible hacker 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 ( 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.
