Amazon Linux 2 : gnupg2 (ALAS-2018-1045)

high Nessus Plugin ID 111605

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

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)

Solution

Run 'yum update gnupg2' to update your system.
