PostgreSQL critical security fix now available
The PostgreSQL developers have released the latest versions of the open source database and revealed the critical security hole which led them to close access to the source code of PostgreSQL last week while the fix was committed. PostgreSQL 9.0, 9.1 and 9.2 are affected, though the developers know of no exploit of the flaw being used in the wild. Users of PostgreSQL 8.4 are unaffected by this particular problem. The developers remind users of earlier versions that they are running unsupported editions of the database and already have un-patched security flaws on their servers.
