    Package : ruby-sanitize
    CVE ID : CVE-2020-4054
    Debian Bug : 963808

    Michal Bentkowski discovered that ruby-sanitize, a whitelist-based HTML sanitizer, is prone to a HTML sanitization bypass vulnerability when
    using the "relaxed" or a custom config allowing certain elements.
    Content in a <math> or <svg> element may not be sanitized correctly even
    if math and svg are not in the allowlist.

    For the stable distribution (buster), this problem has been fixed in
    version 4.6.6-2.1~deb10u1.

    We recommend that you upgrade your ruby-sanitize packages.

    For the detailed security status of ruby-sanitize please refer to its
    security tracker page at: https://security-tracker.debian.org/tracker/ruby-sanitize
