An integer overflow flaw, leading to a heap-based buffer overflow, was found in the PostgreSQL handling code for regular expressions. A remote attacker could use a specially crafted regular expression to cause PostgreSQL to crash or possibly execute arbitrary code.
(CVE-2016-0773)
If the postgresql service is running, it will be automatically restarted after installing this update.
