CVE-2024-52616: Avahi: avahi wide-area dns predictable transaction ids
A flaw was found in the Avahi-daemon, where it initializes DNS transaction IDs randomly only once at startup, incrementing them sequentially after that. This predictable behavior facilitates DNS spoofing attacks, allowing attackers to guess transaction IDs.

Avahi: avahi wide-area dns predictable transaction ids
— Microsoft
The sequential increment of DNS transaction IDs makes Avahi vulnerable to DNS spoofing, allowing attackers to inject malicious DNS records. This can compromise the integrity of DNS responses, redirecting users to potentially harmful domains. This vulnerability poses a greater risk as it directly undermines the integrity of DNS resolution, affecting all systems using Avahi for wide-area DNS queries unless mitigations are applied.
