Adobe and Microsoft today each released software updates to plug dangerous security holes in their products. Adobe pushed patches to fix holes in Adobe Acrobat/Reader as well as Flash Player. Microsoft issued eight update bundles to nix at least 13 security vulnerabilities in Windows and software that runs on top of the operating system.
A majority of the patches released by Microsoft are fixes for products that run in enterprise environments. Chief among the consumer-facing Microsoft updates is cumulative patch for Internet Explorer that fixes a pair of flaws in all supported versions of IE. This patch also includes the emergency update that Microsoft released earlier this month to address a zero-day vulnerability in IE. Microsoft also issued fixes for several Office vulnerabilities. This month’s batch also includes a .NET fix, which in my experience is best installed separately.
Adobe released a fix for its Flash Player software that corrects at least six security flaws. The Flash update brings the media player to v. 220.127.116.11 on Windows and Mac systems, and v. 18.104.22.1689 for Linux users. To see which version of Flash you have installed, check this link.
IE10/IE11 and Chrome should auto-update their versions of Flash. If your version of Flash on Chrome (on either Windows, Mac or Linux) is not yet updated, you may just need to close and restart the browser.
The most recent versions of Flash are available from the Adobe download center, but beware potentially unwanted add-ons, like McAfee Security Scan). To avoid this, uncheck the pre-checked box before downloading, or grab your OS-specific Flash download from here. Windows users who browse the Web with anything other than Internet Explorer will need to apply this patch twice, once with IE and again using the alternative browser (Firefox, Opera, e.g.).
In addition, there is an update available that fixes at least 11 security holes in versions of Adobe Acrobat and Adobe Reader. Windows and Mac users should update to the latest version (11.0.07).
