    Synopsis
    ========
    
    A heap use-after-free flaw in Qt WebEngine at worst might allow an
    attacker to execute arbitrary code.
    
    Background
    ==========
    
    Library for rendering dynamic web content in Qt5 C++ and QML
    applications.
    
    Affected packages
    =================
    
        -------------------------------------------------------------------
         Package              /     Vulnerable     /            Unaffected
        -------------------------------------------------------------------
      1  dev-qt/qtwebengine           < 5.14.1                  >= 5.14.1
    
    Description
    ===========
    
    A use-after-free vulnerability has been found in the audio component of
    Qt WebEngine.
    
    Impact
    ======
    
    A remote attacker could entice a user to open a specially crafted media
    file in an application linked against Qt WebEngine, possibly resulting
    in execution of arbitrary code with the privileges of the process or a
    Denial of Service condition.
    
    Workaround
    ==========
    
    There is no known workaround at this time.
    
    Resolution
    ==========
    
    All Qt WebEngine users should upgrade to the latest version:
    
      # emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-qt/qtwebengine-5.14.1"
