Interaction error in the PostgreSQL JDBC driver before 8.2, when used with a PostgreSQL server with the "standardconformingstrings" option enabled, such as the default configuration of PostgreSQL 9.1, does not properly escape unspecified JDBC statement parameters, which allows remote attackers to perform SQL injection attacks. NOTE: as of 20120330, it was claimed that the upstream developer planned to dispute this issue, but an official dispute has not been posted as of 20121005.
