DESCRIPTION:
Secunia Research has discovered a vulnerability in BrightStor
ARCserve Backup, which can be exploited by malicious people to
compromise a vulnerable system.

The vulnerability is caused due to insufficient validation of
"handle_t" arguments passed to RPC endpoints. Passing object pointers
to procedures that expect different types can result in arbitrary code
execution.

The vulnerability is confirmed in version r11.5 SP4 build 4491. Other
versions may also be affected.

SOLUTION:
Apply patches (please see the CA advisory for details).
