    Several security issues were discovered in the WebKitGTK Web and JavaScript engines. If a user were
    tricked into viewing a malicious website, a remote attacker could exploit a variety of issues related to
    web browser security, including cross-site scripting attacks, denial of service attacks, and arbitrary
    code execution.
