CVE-2007-0556

https://notcve.org/view.php?id=CVE-2007-0556

The query planner in PostgreSQL before 8.0.11, 8.1 before 8.1.7, and 8.2 before 8.2.2 does not verify that a table is compatible with a "previously made query plan," which allows remote authenticated users to cause a denial of service (server crash) and possibly access database content via an "ALTER COLUMN TYPE" SQL statement, which can be leveraged to read arbitrary memory from the server. El planificador de peticiones en PostgreSQL anterior a 8.0.11, 8.1 anterior a 8.1.7, y 8.2 anterior a 8.2.2 no verifica que una tabla sea compatible con un "plan de peticiones realizado previamente", lo cual permite a usuarios autenticados remotamente provocar una denegación de servicio (caída del servidor) y posiblemente acceder a contenido de la base de datos mediante una sentencia SQL "ALTER COLUMN TYPE", lo cual puede ser aprovechado para leer memoria de su elección del servidor. • http://fedoranews.org/cms/node/2554 http://lists.rpath.com/pipermail/security-announce/2007-February/000141.html http://osvdb.org/33302 http://secunia.com/advisories/24028 http://secunia.com/advisories/24033 http://secunia.com/advisories/24042 http://secunia.com/advisories/24050 http://secunia.com/advisories/24057 http://secunia.com/advisories/24151 http://secunia.com/advisories/24315 http://secunia.com/advisories/24513 http://secunia.com/advisories/24577 http://secunia&# •
