| Doc Text: |
A flaw was found in mtr. A remote attacker, by influencing the DNS (Domain Name System) TXT response used for AS (Autonomous System) lookups, can trigger an out-of-bound read vulnerability in the `ipinfo_lookup()` function. This occurs when a DNS response larger than 512 bytes contains a crafted compression pointer in the answer NAME field. Successful exploitation leads to a reliable crash of the mtr application, resulting in a Denial of Service.
