EulerOS 2.0 SP2 : avahi (EulerOS-SA-2019-1734)

critical Nessus Plugin ID 126861

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the version of the avahi packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

 - 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.
 (CVE-2017-6519)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected avahi package.
