Vulnerability Assessment Details

Fedora Core 2 2005-269: krb5

Vulnerability Assessment Summary
Check for the version of the krb5 package

Detailed Explanation for this Vulnerability Assessment

The remote host is missing the patch for the advisory FEDORA-2005-269 (krb5).

Kerberos V5 is a trusted-third-party network authentication system,
which can improve your network's security by eliminating the insecure
practice of cleartext passwords.

Update Information:

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

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 (cve.mitre.org) has assigned
the names CVE-2005-0468 and CVE-2005-0469 to these issues.
