Adobe patches 25 Flash Player security flaws

Google updates Chrome, Microsoft revisits IE10 security update.

Adobe on Monday released an update to fix 25 security flaws affecting all prior versions of Flash Player on all platforms.

The buffer overflow and memory corruption vulnerabilities could crash the application and potentially hand control over the machine to an attacker, Adobe said.

An Adobe spokesperson said in an emailed statement that Adobe was not aware of any attacks in the wild using these flaws.

Affected versions of Flash Player are 11.4.402.278 and earlier versions for Windows and 11.4.402.265 and earlier versions for Macintosh. After the update, Flash Player on both platforms should be 11.4.402.278.

The affected version of Flash on Linux is and should be updated to Updates are also available for Android and vulnerabilities in Adobe AIR.

Updates for Flash Player in Chrome are handled by Google, which released a “stable channel” update for its Chrome browser on Monday carrying updates to Flash Player for Macs (11.4.402.287) and Windows and Linux (, along with fixes for five unrelated browser security flaws.

Microsoft also revised a September security advisory that fixed Flash Player flaws embedded within Internet Explorer 10 on Windows 8 and Windows Server 2012. The flaws Adobe and Microsoft responded to back then were being exploited in targeted attacks via a malicious Word document.

“Today we revised Security Advisory 2755801 to address issues in Adobe Flash Player in Internet Explorer 10, in conjunction with Adobe’s update process,” said Yunsun Wee, director of Microsoft Trustworthy Computing, on Monday.

Last month Wee said Microsoft and Adobe would attempt to synchronise their respective updates and, if the occasional called for it, Microsoft would issue emergency patches for IE/Flash Player outside its usual Patch Tuesday cycle.
