Descriptions

The ssl_decrypt_buf function in library/ssl_tls.c in PolarSSL before 1.2.11 and 1.3.x before 1.3.8 allows remote attackers to cause a denial of service (crash) via vectors related to the GCM ciphersuites, as demonstrated using the Codenomicon Defensics toolkit.

La función ssl_decrypt_buf en library/ssl_tls.c en PolarSSL anterior a 1.2.11 y 1.3.x anterior a 1.3.8 permite a atacantes remotos causar una denegación de servicio (caída) a través de vectores relacionados con los suites de cifrado GCM, tal y como fue demostrado al utilizar el juego de herramientas Codenomicon Defensics.

A flaw was discovered in PolarSSL, a lightweight crypto and SSL/TLS library, which can be exploited by a remote unauthenticated attacker to mount a denial of service against PolarSSL servers that offer GCM ciphersuites. Potentially clients are affected too if a malicious server decides to execute the denial of service attack against its clients.
