Further information is available at the following URL. http://www.oracle.com/database/index.html II. 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. III. ANALYSIS Exploitation allows the attacker to gain root privilege.
