A security firm has found a pair of security bugs in Microsoft’s Windows Mobile which, if exploited, could crash phones and other devices running the software. The vulnerabilities lie in Windows Mobile Internet Explorer and Windows Mobile Pictures and Video, Trend Micro, a Tokyo-based security vendor, said in a pair of security alerts. Viewing a rigged Web page or malicious JPEG image file on a Windows Mobile device will cause it to fail, according to Trend Micro.
