SCA: security update for secure_headers (GHSA-xq52-rv6w-397c)

medium Tenable Cloud Security Plugin ID 423559

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In Secure Headers (RubyGem secure_headers), a directive injection vulnerability is present in versions
 before 3.8.0, 5.1.0, and 6.2.0. If user-supplied input was passed into
 append/override_content_security_policy_directives, a semicolon could be injected leading to directive
 injection. This could be used to e.g. override a script-src directive. Duplicate directives are ignored
 and the first one wins. The directives in secure_headers are sorted alphabetically so they pretty much all
 come before script-src. A previously undefined directive would receive a value even if
 SecureHeaders::OPT_OUT was supplied. The fixed versions will silently convert the semicolons to spaces and
 emit a deprecation warning when this happens. This will result in innocuous browser console messages if
 being exploited/accidentally used. In future releases, we will raise application errors resulting in 500s.
 Depending on what major version you are using, the fixed versions are 6.2.0, 5.1.0, 3.8.0. (CVE-2020-5217)
