Descriptions
PostgreSQL before 9.1.23, 9.2.x before 9.2.18, 9.3.x before 9.3.14, 9.4.x before 9.4.9, and 9.5.x before 9.5.4 allow remote authenticated users to cause a denial of service (NULL pointer dereference and server crash), obtain sensitive memory information, or possibly execute arbitrary code via (1) a CASE expression within the test value subexpression of another CASE or (2) inlining of an SQL function that implements the equality operator used for a CASE expression involving values of different types.
PostgreSQL en versiones anteriores a 9.1.23, 9.2.x en versiones anteriores a 9.2.18, 9.3.x en versiones anteriores a 9.3.14, 9.4.x en versiones anteriores a 9.4.9 y 9.5.x en versiones anteriores a 9.5.4 permiten a usuarios remotos autenticados provocar una denegación de servicio (referencia a puntero NULL y caída del servidor), obtener información de memoria sensible, o posiblemente ejecutar código arbitrario a través de (1) una expresión CASE dentro de la subexpresión de valor de prueba de otro CASE o (2) el inicio de una función SQL que implementa el operador de igualdad utilizado para una expresión CASE que implica valores de diferentes tipos.
A flaw was found in the way PostgreSQL server handled certain SQL statements containing CASE/WHEN commands. A remote, authenticated attacker could use a specially crafted SQL statement to cause PostgreSQL to crash or disclose a few bytes of server memory or possibly execute arbitrary code.
