Oracle9i Database contains buffer overflow in FROM_TZ() function

Vulnerability Note VU#399806

Original Release Date: 2004-02-27 | Last Revised: 2004-02-27

Overview

Oracle9i Database contains a buffer overflow in the FROM_TZ() function which could allow anyone who can query the server to execute arbitrary code or access data with the privileges of the vulnerable process.

Description

A buffer overflow exists in the FROM_TZ() function. This function is responsible for handling time stamp conversions. By supplying an overly long character string to the Time Zone Difference (TZD) parameter of the FROM_TZ() 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.

Impact

Exploitation may result in the ability to execute arbitrary code or access data with the privileges of the vulnerable process.

Solution

According to NGSSoftware, this problem is fixed in Oracle 9i Database Release 2, version 9.2.0.3.
