Oracle Database Server is a family of database
products that range from
personal databases to enterprise solutions. Further

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

II. DESCRIPTION

Local exploitation of an arbitrary file rewrite
vulnerability in Oracle
Corp.'s Oracle Database 10g Release 2 database

The vulnerability exists in a function that allows a
user with an
authenticated session to create any file or rewrite
any files to which
