Descriptions

The x509parse_crt function in x509.h in PolarSSL 1.1.x before 1.1.7 and 1.2.x before 1.2.8 does not properly parse certificate messages during the SSL/TLS handshake, which allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via a certificate message that contains a PEM encoded certificate.

La función x509parse_crt en x509.h de PolarSSL 1.1.x (anteriores a 1.1.7) y 1.2.x (anteriores a 1.2.8) no procesa apropiadamente los mensajes de certificado durante un handshake SSL/TLS, lo que permite a atacantes remotos causar una denegación de servicio (bucle infinito y consumo de CPU) a través de un mensaje de certificado que contiene un certificado codificado en PEM.
