Descriptions

statem/statem.c in OpenSSL 1.1.0a does not consider memory-block movement after a realloc call, which allows remote attackers to cause a denial of service (use-after-free) or possibly execute arbitrary code via a crafted TLS session.

statem/statem.c en OpenSSL 1.1.0a no considera el movimiento de bloque de memoria después de una llamada realloc, lo que permite a atacantes remotos provocar una denegación de servicio (uso después de liberación de memoria) o posiblemente ejecutar código arbitrario a través de una sesión TLS manipulada.
