CVE-2017-6519 (opens in a new tab)How to fix?
Upgrade Alpine:3.19 avahi to version 0.7-r2 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream avahi package and not the avahi package as distributed by Alpine.
See How to fix? for Alpine:3.19 relevant fixed versions and status.
avahi-daemon in Avahi through 0.6.32 and 0.7 inadvertently responds to IPv6 unicast queries with source addresses that are not on-link, which allows remote attackers to cause a denial of service (traffic amplification) and may cause information leakage by obtaining potentially sensitive information from the responding device via port-5353 UDP packets. NOTE: this may overlap CVE-2015-2809.
