BACKGROUND

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.

http://www.oracle.com/database/index.html

DESCRIPTION

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.

ANALYSIS

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".

DETECTION

iDefense confirmed the existence of this vulnerability in Oracle 11g R1 version 11.1.0.6.0 on 32-bit Linux platform. Previous versions may also be affected.

WORKAROUND

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.
