A Malformed h2 frame can cause 'std::out_of_range' exception when parsing priority meta data. This behavior can lead to denial-of-service. This affects all supported versions of HHVM (3.25.2, 3.24.6, and 3.21.10 and below) when using the proxygen server to handle HTTP2 requests. Un frame h2 malformado puede provocar una excepción 'std::out_of_range' durante el análisis de metadatos prioritarios.
