Fedora Core 2 2005-269: krb5 |
||
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.
