Description

The network authentication system in Kerberos 5 contains an RPC library that includes an XDR decoder derived from Sun's RPC implementation. This implemenation is vulnerable to a heap overflow. With Kerberos, it is believed that an attacker would need to be able to successfully authenticate to kadmin to be able to exploit this vulnerability.
