Adobe has issued a patch for an actively targeted flaw in Flash Player that allows an attacker to remotely cause a crash and potentially take control of the targeted system.
Operating systems receiving the update include Windows, Mac OS X, Linux, Solaris and Android, along with Mac OS X, Windows and Unix versions of Adobe Acrobat and Reader.
The vulnerability has been targeted in the wild for attacks on Flash Player in Windows systems only so far.
Adobe has released the patch a week earlier than expected, having originally announced a date of 27 September, two weeks after the vulnerability was first acknowledged.
Users running Flash Player 10.1.82.76 and earlier for Windows, Mac OS X, Solaris and Linux are being advised to update their systems. Android users will have the update applied in Flash Player version 10.1.95.1 and later.
Adobe has also advised users of Adobe Reader and Acrobat versions 9.3.4 and earlier to update their software.
Some Chrome users may already be protected, as Google added a fix for Flash Player into a Chrome security update last week.
