CVE-2018-0739

Constructed ASN.1 types with a recursive definition (such as can be found in PKCS7) could eventually exceed the stack given malicious input with excessive recursion. This could result in a Denial Of Service attack. There are no such structures used within SSL/TLS that come from untrusted sources so this is considered safe. Fixed in OpenSSL 1.1.0h (Affected 1.1.0-1.1.0g). Fixed in OpenSSL 1.0.2o (Affected 1.0.2b-1.0.2n).

Los tipos constructed ASN.1 con una definición recursiva (como la que podemos encontrar en PKCS7) podrían acabar excediendo la pila debido a entradas maliciosas con recursión excesiva. Esto podría dar como resultado un ataque de denegación de servicio (DoS). No hay estructuras de este tipo empleadas en SSL/TLS que provengan de fuentes no fiables, por lo que se consideran seguras. Solucionado en OpenSSL 1.1.0h (versiones 1.1.0-1.1.0g afectadas). Solucionado en OpenSSL 1.0.2o (versiones 1.0.2b-1.0.2n afectadas).
