Descriptions

The asn1_get_bit_der function in GNU Libtasn1 before 3.6 does not properly report an error when a negative bit length is identified, which allows context-dependent attackers to cause out-of-bounds access via crafted ASN.1 data.

La función asn1_get_bit_der en GNU Libtasn1 anterior a 3.6 no informa debidamente de un error cuando una longitud de bit negativa está identificada, lo que permite a atacantes dependientes de contexto causar acceso fuera de rango a través de datos ASN.1 manipulados.
