CVE-2008-0062: Null Pointer Dereference
First published: Wed Mar 19 2008(Updated: )
KDC in MIT Kerberos 5 (krb5kdc) does not set a global variable for some krb4 message types, which allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via crafted messages that trigger a NULL pointer dereference or double-free.
