Adobe and Google have released patch bundles for their respective Flash and Chrome applications.
The Adobe security update fixes critical vulnerabilities in Flash Player 10.1.85.3 and earlier for Windows, Macintosh, Linux and Solaris, and Adobe Flash Player 10.1.95.1 for Android.
Adobe warned about the flaw last week, which is also found in Reader and Acrobat and is being actively exploited by malware writers. Additional patches for Reader and Acrobat should be issued within a week.
"Adobe categorises this as a 'critical' update, and recommends affected users update their installations to the newest versions," said the company.
Google, meanwhile, has released a Chrome Stable Channel Update including 10 patches for the browser, all labelled 'high' risk. Chrome 7.0.517.44 is available for Windows, Mac, Linux and Chrome Frame on the Stable Channel.
The update includes a new version of Flash Player for Chrome, improvements to block memory corruption and changes to frame object handling, text flow and SVG handling.
The Google patch also represents a $7,500 (£4,625) payday for the researchers who uncovered the vulnerabilities under the firm's bug bounty scheme.
