Descriptions

OpenSSL before 0.9.8l, and 0.9.8m through 1.x, does not properly restrict client-initiated renegotiation within the SSL and TLS protocols, which might make it easier for remote attackers to cause a denial of service (CPU consumption) by performing many renegotiations within a single connection, a different vulnerability than CVE-2011-5094. NOTE: it can also be argued that it is the responsibility of server deployments, not a security library, to prevent or limit renegotiation when it is inappropriate within a specific environment

** EN DISPUTA ** OpenSSL anterior a v0.9.8l y v0.9.8m a través de 1.x, no restringen adecuadamente por el cliente dentro de la renegociación de los protocolos SSL y TLS, lo que podría hacer más fácil para los atacantes remotos causar una denegación de servicio (el consumo de CPU) mediante la realización de las renegociaciones de muchos dentro de una sola conexión, una vulnerabilidad diferente a CVE-2011-5094. NOTA: también se puede argumentar que es la responsabilidad de las implementaciones de servidores, no una biblioteca de seguridad, para prevenir o limitar la renegociación cuando es inapropiado dentro de un entorno específico.
