**Description**
The issue relates to insufficient access control within the mDNSResponder daemon. Exploitation may allow an attacker to elevate their privileges. The vulnerability allows for local network eavesdropping and device discovery without authentication. An exploit chain involving mDNSResponder, traceroute6, libinfo, and an integer overflow can lead to root access. A new libmalloc “region-trailer” move and PAC bypass were implemented to address the issue.
