NewStart CGSL MAIN 6.01 : unbound Multiple Vulnerabilities (NS-SA-2020-0037)

high Nessus Plugin ID 138770

Language:

Synopsis

The remote machine is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version MAIN 6.01, has unbound packages installed that are affected by multiple vulnerabilities:

 - Unbound 1.6.4 through 1.9.4 contain a vulnerability in the ipsec module that can cause shell code execution after receiving a specially crafted answer. This issue can only be triggered if unbound was compiled with `--enable-ipsecmod` support, and ipsecmod is enabled and used in the configuration. (CVE-2019-18934)

 - Unbound before 1.10.1 has an infinite loop via malformed DNS answers received from upstream servers.
 (CVE-2020-12663)

 - Unbound before 1.10.1 has Insufficient Control of Network Message Volume, aka an NXNSAttack issue. This is triggered by random subdomains in the NSDNAME in NS records. (CVE-2020-12662)

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 unbound packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
