Adobe to patch Reader zero-day this week with rush update

Gregg Keizer | Feb. 18, 2013
Adobe on Saturday said it would release an emergency patch for two Reader zero-day vulnerabilities this week.

Edell did say that Protected View may be toggled on by default in the future. She did not commit to a timetable, however.

Windows users can turn on Protected View by opening Reader 11, selecting "Preferences" from the Edit menu, clicking the "Security (Enhanced)" item in the column on the left, then near the top of the ensuing dialog clicking "Files from potentially unsafe locations" or "All files" under the "Protected View" heading.

But customers running OS X are out of luck: Reader for Apple's operating system lacks any sandboxing. Until Adobe patches Reader, Mac owners can protect themselves by viewing PDFs in OS X's Preview application rather than Adobe Reader.

To make this change, users can right-click on any PDF document, select "Get Info" from the pop-up menu, choose "Preview" in the "Open with" field, and finally, click the "Change All" button.

The last time Adobe rushed out an emergency update to patch a Reader zero-day vulnerability was in December 2011.
