3) Description of Vulnerability

Secunia Research has discovered a vulnerability in Lotus Notes, which
can be exploited by malicious people to compromise a user's system. 

The vulnerability is caused due to a boundary error in uudrdr.dll when
handling an UUE file containing an encoded file with an overly long
