A Computerworld Windows 7 system, however, was not silently updated to 126.96.36.199, the patched version, within an hour of booting the PC, the interval the tool uses to check for new updates. Adobe was unable to explain the problem, other than to suggest an initial failure by those browsers to connect to its servers. In that case, the silent updater is designed to stop pinging Adobe for 24 hours before resuming.
The current stable version of Chrome -- Google's browser is the only one that includes the Adobe software in its updates -- reports running the patched 188.8.131.52 edition of Flash Player. Google shipped that version of Chrome, 18.0.1025.168, on Monday, April 30, giving it a four-day jump on Adobe's plug-in patching.
It was Chrome's largest-ever lead: previously, Google has beaten Adobe to Flash Player patching by hours, or at most a day.
Adobe today again explained Chrome's faster Flash patching by noting that it hands Flash updates to Google as "soon as we updated the code," but needs more time on its part to test fixes on scores of operating system and browser combinations before it's confident enough to ship the update to all users.
Microsoft's vulnerability research group reported the Flash vulnerability to Adobe.
The patched versions of Flash Player for Windows, Mac, Linux and Solaris can be downloaded from Adobe's website. Windows users can wait for the silent updater to kick in, run Flash's update tool or wait for the software to prompt them that a new version is available.
Android users will be able to download the new version from Google Play, formerly the Android Market, later today, said Adobe.
To determine which version of Flash Player is running in any particular browser, users can steer to this Adobe page.
