CVE-2017-6519 Open this link in a new tabHow to fix?
Upgrade Debian:unstable avahi to version 0.7-5 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 Debian.
See How to fix? for Debian:unstable 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.
