Some vulnerabilities have been reported in various CA products, which can be exploited by malicious people to compromise a vulnerable system.

1) Some boundary errors exist within RPC routines in the Backup Agent RPC Server (DBASRV.exe), which can be exploited to cause stack-based buffer overflows and allow arbitrary code execution.

2) A boundary error exists in ASBRDCST.DLL when processing Discovery Service communication. This can be exploited to cause a stack-based buffer overflow and allows execution of arbitrary code.

3) Two boundary errors exist within RPC routines in ASCORE.dll, used by the Message Engine RPC Server. These can be exploited to cause a heap-based buffer overflow and a stack-based buffer overflow by passing an overly long string as the second parameter, and allow arbitrary code execution.

The following products for the Windows platform are affected:
* BrightStor ARCserve Backup r11.5 SP1 and below (SP2 is not affected)
* BrightStor ARCserve Backup r11.1
* BrightStor ARCserve Backup for Windows r11
* BrightStor Enterprise Backup 10.5
