Descriptions

OpenSSL 0.9.6 and 0.9.7 does not properly track the number of characters in certain ASN.1 inputs, which allows remote attackers to cause a denial of service (crash) via an SSL client certificate that causes OpenSSL to read past the end of a buffer when the long form is used.

OpenSSL 0.9.6 y 0.9.7no lleva bien la cuenta del número de caractéres de ciertas entradas ASN.1, lo que permite a atacantes remotos causar una denegación de servicio (caída) mediante un certifiucado que hace que OpenSSL lea más allá del búfer cuando una forma larga es usada.
