Descriptions

Multiple integer signedness errors in crypto/buffer/buffer.c in OpenSSL 0.9.8v allow 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. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-2110.

Múltiples errores de signo en enteros en crypto/buffer/buffer.c en OpenSSL v0.9.8v permite a atacantes remotos realizar ataques de desbordamiento de buffer, y provocar una denegación de servicio (corrupción de memoria) o posiblemente tener otro impacto no especificado, a través de datos DER modificados, como se demuestra con un certificado X.509 o una clave pública RSA. NOTA: esta vulnerabilidad existe debido a una solución incompleta para CVE-2012-2110.
