Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Denial of Service: Insufficent frame length and window increment validation in HTTP/2 WINDOW_UPDATE frames, as well as weak body length checks in PRIORITY frames, can lead to parser crashes or unexpected behavior.
Protocol Violation: Improper validation of the promised stream identifier in PUSH_PROMISE frames could allow violations of the HTTP/2 specification, leading to downstream connection synchronization issues.
