Synopsis:	Important: krb5 security update
Issue date:	2009-04-07
CVE Names:	CVE-2009-0844 CVE-2009-0845 CVE-2009-0846

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. A remote attacker
could use these flaws to crash any network service utilizing the MIT
Kerberos GSS-API library to authenticate users or, possibly, leak
portions of the service's memory. (CVE-2009-0844, CVE-2009-0845)
