critical Tenable Self-Hosted Container Security Plugin ID 403601

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2017-6519)
