CVE-2009-1378

Múltiples fugas de memoria en la función dtls1_process_out_of_seq_message en ssl/d1_both.c en OpenSSL v0.9.8k y anteriores permite a atacantes remotos producir una denegación de servicio (consumo de memoria) a través de registros DTLS que (1) son duplicados o (2) tienen una secuencia de números mucho mayor que la actual secuencia de números, conocido también como "fuga de memoria en el manejo de fragmentos DTLS".

It was discovered that OpenSSL did not limit the number of DTLS records it would buffer when they arrived with a future epoch. A remote attacker could cause a denial of service via memory resource consumption by sending a large number of crafted requests. It was discovered that OpenSSL did not properly free memory when processing DTLS fragments. A remote attacker could cause a denial of service via memory resource consumption by sending a large number of crafted requests. It was discovered that OpenSSL did not properly handle certain server certificates when processing DTLS packets. A remote DTLS server could cause a denial of service by sending a message containing a specially crafted server certificate. It was discovered that OpenSSL did not properly handle a DTLS ChangeCipherSpec packet when it occurred before ClientHello. A remote attacker could cause a denial of service by sending a specially crafted request. It was discovered that OpenSSL did not properly handle out of sequence DTLS handshake messages. A remote attacker could cause a denial of service by sending a specially crafted request.
