Description:
In responder vendor-defined large-payload processing, robustness relies partly on assertions for header-capacity assumptions before subtraction/use, instead of fully runtime-enforced error handling.
Observed Behavior
Request checks are primarily lower-bound style.
Response-header capacity guard is assertion-based in key point(s).
Runtime behavior robustness is partially tied to assert-enabled builds/contracts.
Expected Behavior
All capacity and structural preconditions should be runtime-validated with explicit protocol error returns, independent of assertion behavior.
Impact
Robustness and deterministic error-path consistency gap.
Different safety posture between assert and non-assert contexts.
Severity
Medium (robustness/implementation-hardening issue, non-security by itself).
Suggested Fix
Add explicit runtime guards for header-capacity and large-payload structural consistency before arithmetic/use; return explicit protocol errors on invalid combinations. Add UT for boundary buffers and malformed length combos.
Present in Release 3.8.2
Not in identical 1.4 large-payload form, but similar assertion-dependent header-capacity pattern exists in older vendor responder flow.
