Description Robert Frohl 2019-08-14 09:33:32 UTC
CVE-2019-9516

Some HTTP/2 implementations are vulnerable to a header leak, potentially leading
to a denial of service. The attacker sends a stream of headers with a 0-length
header name and 0-length header value, optionally Huffman encoded into 1-byte or
greater headers. Some implementations allocate memory for these headers and keep
the allocation alive until the session dies. This can consume excess memory.
