Description Andrej Nemec 2016-02-15 09:48:48 UTC
A vulnerability was found in a way nghttp2 processes incoming packets.
Nghttpd, nghttp, and libnghttp2_asio applications do not limit the
memory usage for the incoming HTTP header field. If peer sends
specially crafted HTTP/2 HEADERS frames and CONTINUATION frames, they
will crash with out of memory error.
