PostgreSQL enum_recv() denial of service
|postgresql-enumrecv-dos (81917)||Medium Risk|
PostgreSQL is vulnerable to a denial of service, caused by the improper validation of input by the enum_recv() function. A remote attacker could exploit this vulnerability using a specially-crafted query to cause the server to crash.
Denial of Service
Upgrade to the latest version of PostgreSQL (8.3.23, 8.4.16, 9.0.12, 9.1.8, or 9.2.3 or later), available from the PostgreSQL Web site. See References.

- CVE-2013-0255: PostgreSQL 9.2.x before 9.2.3, 9.1.x before 9.1.8, 9.0.x before 9.0.12, 8.4.x before 8.4.16, and 8.3.x before 8.3.23 does not properly declare the enum_recv function in backend/utils/adt/enum.c, which causes it to be invoked with incorrect arguments and allows remote authenticated users to cause a denial of service (server crash) or read sensitive process memory via a crafted SQL command, which triggers an array index error and an out-of-bounds read.
