Synopsis

Description

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6849-1 advisory.

 It was discovered that Salt incorrectly validated method calls and sanitized paths. A remote attacker could possibly use this issue to access some methods without authentication. (CVE-2020-11651, CVE-2020-11652)
