NewStart CGSL CORE 5.04 / MAIN 5.04 : avahi Vulnerability (NS-SA-2020-0058)

critical Nessus Plugin ID 143938

Synopsis

The remote machine is affected by a vulnerability.

Description

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has avahi packages installed that are affected by a 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. NOTE: this may overlap CVE-2015-2809. (CVE-2017-6519)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the vulnerable CGSL avahi packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
