Oracle9i Database contains a buffer overflow in the TIME_ZONE session parameter which could allow anyone who can query the server to execute arbitrary code or access data with the privileges of the vulnerable process.
The TIME_ZONE parameter is a session parameter that specifies the local time zone displacement for the current SQL session. A buffer overflow exists in the TIME_ZONE parameter. By supplying an overly long character string to the function, an attacker could overwrite a return address on the stack, resulting in the ability to execute arbitrary code or access data with the privileges of the vulnerable process. Oracle typically runs as SYSTEM on Windows and as the ORACLE user on UNIX.
Exploitation may result in the ability to execute arbitrary code or access data with the privileges of the vulnerable process.
According to NGSSoftware, this problem is fixed in Oracle 9i Database Release 2, version 220.127.116.11.
This vulnerability was reported by NGSSoftware.
