-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Hewlett Packard StorageWorks Storage
Mirroring. Authentication is not required to exploit this
vulnerability.

The specific flaw exists in the DoubleTake.exe process bound by default
on TCP ports 1100, 1106 and UDP port 1105. During the handling of an
encoded authentication request, the process copies the user-supplied
login information into a fixed length stack buffer. Sending at least 256
bytes will trigger a stack based buffer overflow due to a vulnerable
processing loop. Exploitation of this issue can result in arbitrary code
execution.

-- Vendor Response:
Hewlett-Packard states:
To resolve this vulnerability download HP StorageWorks Storage Mirroring
software v4.5 Service Pack 2 (SP2) from Double-Take at the following
URL: http://www.doubletake.com/products/double-take/default.aspx
