Adobe on Friday issued an emergency patch for a critical bug in its Flash Player software that is being used in targeted malware attacks.
Updating to Flash version 184.108.40.206 for Windows, Macintosh and Linux closes an "object confusion" vulnerability that, if exploited, could cause an application crash or, worse, lead to the takeover of a system, according to a bulletin.
Attackers are attempting to exploit the vulnerability via email attachments. Right now, only users of Internet Explorer for Windows are being hit.
Flash for Android-based mobile devices also have been updated. If the software is installed on Google's Chrome browser, it automatically was updated so users don't need to take any action.
Users are advised to patch as soon as possible.
