Vulnerability Name:

CVE-2017-6519 (CCN-128566)

Assigned:2015-03-31
Published:2015-03-31
Updated:2020-07-29
Summary: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.
