An input validation flaw was found in the ASN.1 (Abstract Syntax Notation One) decoder used by MIT Kerberos. A remote attacker could use this flaw to crash a network service using the MIT Kerberos library, such as kadmind or krb5kdc, by causing it to dereference or free an uninitialized pointer. (CVE-2009-0846)Multiple input validation flaws were found in the MIT Kerberos GSS-API library's implementation of the SPNEGO mechanism.
