CVSS 3.1 Score 9.8 of 10 (high)
Details
Summary
CVE-2016-20021 is a critical vulnerability that affects Gentoo Portage before version 3.0.47. The vulnerability occurs due to missing PGP validation of executed code in the standalone emerge-webrsync tool, which does not perform signature verification for downloaded .gpgsig files. It should be noted that Portage is only vulnerable if emerge-webrsync is used. The potential danger of this vulnerability to an organization is high, as it could allow an attacker to execute malicious code without detection or authentication. To remediate the vulnerability, users should update Gentoo Portage to version 3.0.47 or above and ensure that PGP validation and signature verification are properly implemented for downloaded files.
