Overview
Affected versions of this package are vulnerable to Always-Incorrect Control Flow Implementation due to the sendOverloadError function. An attacker can cause the application to crash by triggering a reset during the message begin phase, leading to a null pointer dereference. This is only exploitable if envoy.load_shed_points.http1_server_abort_dispatch is configured.
Workaround
This vulnerability can be mitigated by disabling http1_server_abort_dispatch load shed point or using a high threshold.
