4) Description of Vulnerability

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

The vulnerability is caused due to an integer overflow when processing
the number of dimensions in an array of variant types received as
part of an RPC request. This can be exploited to cause a heap-based
buffer overflow by specifying an overly large number of array
dimensions.

Successful exploitation allows execution of arbitrary code.

======================================================================
5) Solution

Update to Orb 2.00.1084.

The vulnerability is also addressed in Winamp Remote BETA 2.00.1024.
