Descriptions
Multiple race conditions in ssl/t1_lib.c in OpenSSL 0.9.8f through 0.9.8o, 1.0.0, and 1.0.0a, when multi-threading and internal caching are enabled on a TLS server, might allow remote attackers to execute arbitrary code via client data that triggers a heap-based buffer overflow, related to (1) the TLS server name extension and (2) elliptic curve cryptography.
Múltiples vulnerabilidades de condición de carrera en ssl/t1_lib.c en OpenSSL v0.9.8f a la v0.9.8o, v1.0.0, y v1.0.0a, cuando la multi-hilo la caché interna está activada en el servidor TLS, podría permitir a atacantes remotos ejecutar código de su elección a través de datos del cliente que provocan un desbordamiento de búfer basado en memoria dinámica (heap), relacionado con (1)el nombre de extensión del servidor TLS y (2) la curva elíptica criptográfica.
A flaw has been found in the OpenSSL TLS server extension code parsing which on affected servers can be exploited in a buffer overrun attack. All versions of OpenSSL supporting TLS extensions contain this vulnerability including OpenSSL 0.9.8f through 0.9.8o, 1.0.0, 1.0.0a releases. Any OpenSSL based TLS server is vulnerable if it is multi-threaded and uses OpenSSL's internal caching mechanism. Servers that are multi-process and/or disable internal session caching are NOT affected. In particular the Apache HTTP server (which never uses OpenSSL internal caching) and Stunnel (which includes its own workaround) are NOT affected.
