Description: Several vulnerabilities have been reported in BrightStor ARCserve Backup, which can be exploited by malicious people to compromise a vulnerable system. 1) An error in the handling of opnum 0xBF RPC requests within the Tape Engine service can be exploited to execute arbitrary code via a specially crafted RPC request sent to the service (default port 6502/TCP). 2) A boundary error in the handling of opnum 0x2F and opnum 0x75 RPC requests within the Message Engine RPC service can be exploited to cause a buffer overflow via a specially crafted RPC request sent to the service (default ports 6503/TCP and 6504/TCP). 3) A boundary error in the handling of opnum 0xCF RPC requests to the Tape Engine RPC service can be exploited to cause a buffer overflow via a specially crafted RPC request sent to the service (default port 6503/TCP). 4) Two boundary errors in the handling of RPC requests within the Mediasrv.exe service can be exploited to cause a stack-based buffer overflow via a specially crafted RPC request sent to the service. 5) A boundary error within ASCORE.dll when handling opnum 0x2F RPC requests within the Message Engine RPC service can be exploited to cause a stack-based buffer overflow via a specially crafted RPC request sent to the service (default ports 6503/TCP and 6504/TCP). Successful exploitation of the vulnerabilities allow execution of arbitrary code.
