Windows 8 testers using Microsoft's Internet Explorer 10 browser risk running afoul of security exploits, as critical vulnerabilities in Adobe's Flash remain unresolved. Microsoft's decision to bake Flash directly into Internet Explorer 10 leaves the browser at risk: Adobe closed the security hole with a patch in August, but the browser will remain susceptible until Microsoft releases an update of their own. The flaw could cause Flash to crash, and allow an attacker to take control of a user's system. Fortunately, sidestepping it is simple: use another browser, or disable Flash. The company told ZDNet that Windows 8 won't be receiving that update until the operating system is available to the general public on October 26th.
