Vulnerability details

The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to improper error handling in the HTTP/2 server when receiving a malformed HEADERS frame with oversized invalid HPACK data. A remote attacker can send a specially crafted HTTP/2 HEADERS frame to cause a denial of service.

This primarily affects applications that do not attach explicit error handlers to secure sockets.
