high Nessus Plugin ID 127393

Language:

Synopsis

The remote machine is affected by a vulnerability.

Description

The remote NewStart CGSL host, running version MAIN 4.05, has gnupg2 packages installed that are affected by a vulnerability:

 - A data validation flaw was found in the way gnupg processes file names during decryption and signature validation. An attacker may be able to inject messages into gnupg verbose message logging which may have the potential to bypass the integrity of signature authentication mechanisms and could have other unintended consequences if applications take action(s) based on parsed verbose gnupg output. (CVE-2018-12020)

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 gnupg2 packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
