Oracle Database Local Untrusted Library Path Vulnerability

Oracle Database Server is "a family of database products that range from personal databases to
enterprise solutions". Local exploitation of an untrusted library path vulnerability in Oracle Corp.'s Oracle Database product allows attackers to gain elevated privileges.


Vulnerable Systems:
* Oracle 11g R1 version on 32-bit Linux platform

Immune Systems:

This vulnerability specifically exists in a set-uid root program
distributed with Oracle Database for Linux and Unix platforms. By
replacing a module owned by the oracle user, which is loaded by this
program, an attacker can execute arbitrary code as root.

Exploitation allows the attacker to gain root privilege. In order to
exploit the vulnerability, the attacker must have access to database owner
account, typically "oracle", or be a member of oracle installation group,
typically "oinstall".

In order to prevent exploitation, administrators can remove the set-uid
bit from the vulnerable program. However, doing so could impair the
functionality of the DBMS_SCHEDULER package.

Vendor response:
Oracle Corp. has addressed this vulnerability with the release of their
July 2008 Critical Patch Update. For more information, visit the following
