"value": "ESP-Protocols is a collection of protocol components for ESP-IDF. Prior to mDNS version 1.11.2, the `mdns` component follows DNS name-compression pointers recursively when parsing fully qualified domain names (FQDNs) in inbound mDNS packets without capping pointer-follow depth in `mdns_utils_read_fqdn()`. An unauthenticated attacker on the same link-local network can send a crafted packet to UDP port 5353 on an `ESP-IDF` device using `espressif/mdns` with mDNS enabled. Deep recursion exhausts the fixed-size stack of the mDNS FreeRTOS task, causing a controlled panic and reboot; persistent malicious traffic can cause a crash loop. No confidentiality or integrity impact has been demonstrated, and remote code execution is not claimed. This issue is fixed in mDNS version 1.11.2."
