schreibfaul1 ESP32-audioI2S 3.4.5 has a heap-based buffer overflow vulnerability in the host parsing logic. The dismantle_host() function parses untrusted host and URL input, and subsequent code uses clone_from() to copy parsed host, request host, extension and query_string segments into fixed heap buffers without boundary checking.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
