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

The specific flaw exists within FastBackServer.exe which listens by
default on TCP port 1320. When handling a packet with header type
0xFAFBFCFD the process blindly copies user supplied data into a heap
buffer. A remote attacker can exploit this vulnerability to execute
arbitrary code under the context of the SYSTEM user.
