Description :
Kerberos V5 is a trusted-third-party network authentication system,

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
