Descriptions

The xdr_status_vector function in Firebird before 2.1.7 and 2.5.x before 2.5.3 SU1 allows remote attackers to cause a denial of service (NULL pointer dereference, segmentation fault, and crash) via an op_response action with a non-empty status.

La función xdr_status_vector en Firebird anterior a 2.1.7 y 2.5.x anterior a 2.5.3 SU1 permite a atacantes remotos causar una denegación de servicio (referencia a puntero nulo, fallo de segmentación y caída) a través de una acción op_response con un estado 'no vacío'.

It was discovered that Firebird incorrectly handled certain malformed packets. A remote attacker could possibly use this issue with a specially crafted network packet to cause Firebird to crash, resulting in a denial of service. It was discovered that Firebird incorrectly handled certain UDF libraries. A remote attacker could possibly use this issue to execute arbitrary code. Various other issues were also addressed.
