The lack of additional detail in this very sparse announcement really compromises users' ability to damage control effectively.

Would like to know if an installation is vulnerable if:

    1) If Applications, PDF is set to "Always ask"
    2) Ublock and/or privoxy are used
    3) Javascript is disabled
    4) pdfjs.previousHandler.alwaysAskBeforeHandling == false
    5) pdfjs.disabled == true

Also which advertising network and which Russian site would be helpful for blocklists.
