Adobe Flash Player Critical Security Update Released

Adobe Flashplayer

Adobe has released Version of Adobe Flash Player.  These updates address critical vulnerabilities that could lead to remote code execution in Adobe Flash Player and earlier versions.  Successful exploitation could potentially allow an attacker to take control of the affected system. 

In particular, the update addresses CVE-2018-4878 which exists in the wild, and is being used in limited, targeted attacks against Windows users.  These attacks leverage Office documents with embedded malicious Flash content distributed via email. Also included in the update are functional fixes.

Release date:  February 6, 2018
Vulnerability identifier: APSB18--03
Platform:  Windows, Macintosh, Linux and Chrome OS


*Important Note:  Downloading the update from the Adobe Flash Player Download Center link includes a pre-checked option to install unnecessary extras, such as McAfee Scan Plus or Google Drive.  If you use the download center, uncheck any unnecessary extras that you do not want.  They are not needed for the Flash Player update.

    Verify Installation

    To verify the Adobe Flash Player version number installed on your computer, go to the About Flash Player page, or right-click on content running in Flash Player and select "About Adobe Flash Player" from the menu. 

    Do this for each browser installed on your computer.

    To verify the version of Adobe Flash Player for Android, go to Settings > Applications > Manage Applications > Adobe Flash Player x.x.

    Pale Moon Version 27.7.2 Released

    Pale Moon
    Pale Moon has been updated to Version 27.7.2. This is a security and stability update.

    Linux versions will follow shortly.  Details from the Release Notes:

    • Changed the X-Content-Type-Options: nosniff behavior to only check "success" class server responses, for web compatibility reasons.
    • Changed the performance timer resolution once more to a granularity of 1 ms, after evaluating more potential ways of abusing Spectre.
      This takes the most cautious approach possible lacking more information (because apparently NDAs have been signed over this between mainstream players), follows Safari's lead, and should make it not just infeasible but downright impossible to use these timers for nefarious purposes in this context.
    • Improved the debug-only startup cache wrapper to prevent a rare crash.
    • Fixed a crash in the XML parser.
    • Added a check for integer overflow in AesTask::DoCrypto() (CVE-2018-5122) DiD
    • Fixed a potential race condition in the browser cache.
    • Fixed a crash in HTML media elements (CVE-2018-5102)
    • Fixed a crash in XHR using workers.
    • Fixed a crash with some uncommon FTP operations.
    • Fixed a potential race condition in the JAR library.
    *DiD This means that the fix is "Defense-in-Depth": It is a fix that does not apply to a (potentially) actively exploitable vulnerability in Pale Moon, but prevents future vulnerabilities caused by the same code, e.g. when surrounding code changes, exposing the problem, or when new attack vectors are discovered. 
         Minimum system Requirements (Windows):
        • Windows Vista/Windows 7/8/10/Server 2008 or later
        • Windows Platform Update (Vista/7) strongly recommended
        • A processor with SSE2 instruction support
        • 256 MB of free RAM (512 MB or more recommended)
        • At least 150 MB of free (uncompressed) disk space
        Pale Moon includes both 32- and 64-bit versions for Windows:


        To get the update now, select "Help" from the Pale Moon menu at the upper left of the browser window.  Select About Pale Moon > Check for Updates.
