Google on Tuesday updated Chrome to close a zero-day flaw in the web browser's version of Adobe Flash Player, ahead of rival browsers Internet Explorer, Firefox, Safari and Opera – and even ahead of Adobe itself. Chrome 10.0.648.134 contains an updated build of Flash Player, which Google received for integration and testing as part of a collaboration with Adobe, an Adobe spokeswoman told on Thursday. Meanwhile, Adobe on Monday warned that attackers currently are exploiting the flaw through malicious Microsoft Excel files. The software maker is finalizing a fix and plans to patch Flash for Windows, Mac OS X and Linux next week.
