Buffer overflow in the Tape Engine (tapeeng.exe) in CA (formerly Computer Associates) BrightStor ARCserve Backup 11.5 and earlier allows remote attackers to execute arbitrary code via certain RPC requests to TCP port 6502.

Buffer overflow in the BrightStor Backup Discovery Service in multiple CA products, including ARCserve Backup r11.5 SP1 and earlier, ARCserve Backup 9.01 up to 11.1, Enterprise Backup 10.5, and CA Server Protection Suite r2, allows remote attackers to execute arbitrary code via unspecified vectors.

The RPC service in mediasvr.exe in CA BrightStor ARCserve Backup 11.5 SP2 build 4237 allows remote attackers to execute arbitrary code via crafted xdrhandlet data in RPC packets, which is used in calculating an address for a function call, as demonstrated using the 191 (0xbf) RPC request.

The RPC Server service (catirpc.exe) in CA (formerly Computer Associates) BrightStor ARCserve Backup 11.5 SP2 and earlier allows remote attackers to cause a denial of service (service crash) via a crafted TADDR2UADDR that triggers a null pointer dereference in catirpc.dll, possibly related to null credentials or verifier fields.
