VUL-0: CVE-2019-9516: nginx: HTTP/2 implementation is vulnerable to a header leak, potentially leading to a denial of service
Last modified: 2021-03-19 08:05:39 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.
