A group of developers of popular open database PostgreSQL today released security fixes for all currently supported versions of PostgreSQL, including 9.2.3, 9.1.8, 9.0.12, 8.4.16 and 8.3.23.
In all versions, the developers fix the vulnerability, which in use could lead to attacks such as Denial-of-Service. All users are encouraged to upgrade to the new version as soon as possible.
Correction eliminates the previously identified problems in the security CVE-2013-0255, which allowed an authenticated user to cause a server crash caused by the internal function with an invalid parameter.
In addition, some developers have modified the server code Postgres, that when a database with dynamic queries do not slow you down. Was also increased the speed of the operator EXECUTE (in PL / pgSQL), Create / Drop Index Concurrently and elsewhere.
In addition to this, the developers have eliminated about two dozen minor flaws and introduced new time zones in the server database.
