Descriptions

The ASN.1 implementation in OpenSSL before 1.0.1o and 1.0.2 before 1.0.2c allows remote attackers to execute arbitrary code or cause a denial of service (buffer underflow and memory corruption) via an ANY field in crafted serialized data, aka the "negative zero" issue.

La implementación ASN.1 en OpenSSL en versiones anteriores a 1.0.1o y 1.0.2 en versiones anteriores a 1.0.2c permite a atacantes remotos ejecutar código arbitrario o provocar una denegación de servicio (desbordamiento inferior de buffer y corrupción de memoria) a través de un campo ANY en datos serializados manipulados, también conocido como el problema "cero negativo".

A flaw was found in the way OpenSSL encoded certain ASN.1 data structures. An attacker could use this flaw to create a specially crafted certificate which, when verified or re-encoded by OpenSSL, could cause it to crash, or execute arbitrary code using the permissions of the user running an application compiled against the OpenSSL library.
