Critical security updates released for Adobe Flash and Acrobat/Reader on July 10, 2018

On July 10, 2018, Adobe released security updates for Adobe Flash[1] and Acrobat/Reader[2] to fix several critical vulnerabilities. These vulnerabilities can lead to remote-code execution, and should be remediated as quickly as possible.

Systems managed by ISC's IBM Endpoint Manager ("BigFix") can expect to be patched for this vulnerability shortly. Systems administrators of other endpoint management solutions are strongly encouraged to push this patch to their deployments.

For users in unmanaged environments, ISC strongly recommends configuring the software to use Adobe's automatic update for Flash Player. Available for both Windows and macOS, this update check can be configured either to alert the user to the availability of an update or to automatically install any available Flash Player update. The settings can be found in these locations:

  • Windows: Click Start > Settings > Control Panel > Flash Player
  • macOS: System Preferences > Flash Player (note: under "Other")

Both Google Chrome (on Windows and macOS) and Internet Explorer 10/11 (on Windows 10/8.x) manage and update their Flash Player instances within the browser. Windows 7 users of Internet Explorer 10/11 must manually download and install the plug-in for Flash Player. All web browsers should be restarted following the update.

Adobe notes that users who selected the option to 'Allow Adobe to install updates' will receive the update automatically. Users who do not have the 'Allow Adobe to install updates' option enabled can install the update via the update mechanism within the product when prompted.
