PostgreSQL における セキュリティ制限迂回および権限昇格の脆弱性
http://www.postgresql.org/about/news.1170

The PostgreSQL Project today released minor versions updating all active branches of the PostgreSQL object-relational database system, including versions 8.4.2, 8.3.9, 8.2.15, 8.1.19, 8.0.23, and 7.4.27. This release fixes one moderate-risk and one low-risk security issue: an SSL authentication issue, and a privilege escalation issue with expression indexes. All PostgreSQL database administrators are urged to update your version of PostgreSQL at the earliest opportunity.
