Critical Flash Player Update Plugs 11 Holes — Krebs on Security
Adobe has released another batch of security updates for its ubiquitous Flash Player software. This “critical” patch fixes at least 11 vulnerabilities, including one that reports suggest is being exploited in targeted email attacks.
The vulnerabilities exist in Flash versions 10.2.159.1 and earlier for Windows, Mac, Linux and Solaris. To learn which version of Flash you have, visit this link. The new version for most platforms is 10.3.181.14; Android users should upgrade to Flash Player 10.3.185.21 available by browsing to the Android Marketplace on an Android phone; Google appears to have updated Chrome users automatically with this version of Flash back on May 6 (Chrome versions 11.0.696.68 and later have the newest Flash version).
Remember that if you use Internet Explorer
in addition to other browsers, you will need to apply this update
twice: Once to install the Flash Active X plugin for IE, and again to
update other browsers, such as Firefox and Opera. Updates are available by browsing with the appropriate browser to the Flash Player Download Center.
Bear in mind that updating via the Download Center involves installing
Adobe’s Download Manager, which may try to foist additional software.
If you’d prefer to update manually, the direct installers for Windows
should be available at this link. If you run into problems installing this update, you’ll want to uninstall previous versions of Flash Player and then try again.
