    Package        : ruby-sanitize
    CVE ID         : CVE-2018-3740
    Debian Bug     : 893610
    
    The Shopify Application Security Team discovered that ruby-sanitize, a
    whitelist-based HTML sanitizer, is prone to a HTML injection
    vulnerability. A specially crafted HTML fragment can cause to allow non-
    whitelisted attributes to be used on a whitelisted HTML element.
    
    For the stable distribution (stretch), this problem has been fixed in
    version 2.1.0-2+deb9u1.
    
    We recommend that you upgrade your ruby-sanitize packages.
