Details follow: Michael Fuhr discovered an incorrect type check when handling unknown literals. By attempting to coerce such a literal to the ANYARRAY type, a local authenticated attacker could cause a server crash. (CVE-2006-5541) Josh Drake and Alvaro Herrera reported a crash when using aggregate functions in UPDATE statements. A local authenticated attacker could exploit this to crash the server backend. This update disables this construct, since it is not very well defined and forbidden by the SQL standard. (CVE-2006-5540) Sergey Koposov discovered a flaw in the duration logging. This could cause a server crash under certain circumstances. (CVE-2006-5542) Please note that these flaws can usually not be exploited through web and other applications that use a database and are exposed to untrusted input, so these flaws do not pose a threat in usual setups.
