Multiple stack-based buffer overflows in waHTTP.exe (aka the SAP DB Web Server) in SAP DB, possibly 7.3 through 7.5, allow remote attackers to execute arbitrary code via (1) a certain cookie value; (2) a certain additional parameter, related to sapdbwa_GetQueryString; and other unspecified vectors related to "numerous other fields."

The (1) instdbmsrv and (2) instlserver programs in SAP DB Development Tools 7.x trust the user-provided INSTROOT environment variable as a path when assigning setuid permissions to the lserver program, which allows local users to gain root privileges via a modified INSTROOT that points to a malicious dbmsrv or lserver program.

Race condition in SDBINST for SAP database 7.3.0.29 creates critical files with world-writable permissions before initializing the setuid bits, which allows local attackers to gain root privileges by modifying the files before the permissions are changed.
