Overview

Affected versions of this package are vulnerable to Out-of-bounds Read due to the dns_resolve_name_internal process reading past the end of a string when checking for the ".local" mDNS suffix. An attacker can cause a denial of service by supplying a specially crafted hostname that triggers an out-of-bounds read, potentially leading to a fault if the over-read crosses an unmapped memory boundary. This is only exploitable if the system is configured with CONFIG_MDNS_RESOLVER enabled.
