Descriptions

In the course of decompressing HPACK inside the HTTP2 protocol, an unexpected sequence of header table resize operations can place the header table into a corrupted state, leading to a use-after-free condition and undefined behavior. This issue affects Proxygen from v0.29.0 until v2017.04.03.00.

En el curso de una descompresión HPACK dentro del protocolo HTTP2, una secuencia no prevista de operaciones de cambio de tamaño de la tabla de encabezado puede colocar la tabla de encabezado en un estado corrupto, lo que conlleva a una condición de uso de la memoria previamente liberada y un comportamiento no definido. Este problema afecta a Proxygen desde la versión v0.29.0 hasta v2017.04.03.00.
