An unspecified vulnerability in Java SE could allow an unauthenticated attacker to cause no confidentiality impact, high integrity impact, and no availability impact.

A flaw was found in HTTP/2. An attacker, sending a stream of header with a 0-length header name and a 0-length header value, could cause some implementations to allocate memory for these headers and keep the allocations alive until the session dies. The can consume excess memory, potentially leading to a denial of service. The highest threat from this vulnerability is to system availability.
