Oracle Database Server is a family of database products that range from personal databases to enterprise solutions. Further information is available at the following URL.
Local exploitation of an untrusted library path vulnerability in Oracle Corp.'s Oracle Database product allows attackers to gain elevated privileges.
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".
iDefense confirmed the existence of this vulnerability in Oracle 11g R1 version 188.8.131.52.0 on 32-bit Linux platform. Previous versions may also be affected.
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.
Oracle Corp. has addressed this vulnerability with the release of their July 2008 Critical Patch Update. For more information, visit the following URL.
