Descriptions

PostgreSQL 8.4.x before 8.4.11, 9.0.x before 9.0.7, and 9.1.x before 9.1.3 truncates the common name to only 32 characters when verifying SSL certificates, which allows remote attackers to spoof connections when the host name is exactly 32 characters.

PostgreSQL v8.4.x antes de v8.4.11, v9.0.x antes de v9.0.7, y v9.1.x antes de v9.1.3 trunca el nombre común a sólo 32 caracteres en la verificación de los certificados SSL, lo que permite a atacantes remotos falsificar conexiones cuando el nombre de host es exactamente de 32 caracteres.
