Descriptions

The asn1_d2i_read_bio function in crypto/asn1/a_d2i_fp.c in OpenSSL before 0.9.8v, 1.0.0 before 1.0.0i, and 1.0.1 before 1.0.1a does not properly interpret integer data, which allows remote attackers to conduct buffer overflow attacks, and cause a denial of service (memory corruption) or possibly have unspecified other impact, via crafted DER data, as demonstrated by an X.509 certificate or an RSA public key.

La función asn1_d2i_read_bio en OpenSSL antes de v0.9.8v, en v1.0.0 antes de v1.0.0i y en v1.0.1 antes de v1.0.1a no interpreta correctamente los enteros, lo que permite realizar ataques de desbordamiento de buffer a atacantes remotos, y provocar una denegación de servicio (por corrupción de memoria) o posiblemente tener un impacto no especificado, a través de datos DER debidamente modificados, como lo demuestra un certificado X.509 o una clave pública RSA.
