Two companies have released their own unofficial patches for the newly-disclosed Internet Explorer vulnerability that is rapidly being exploited in the wild. Security firms eEye and Determina have both announced the availability of unofficial hotfixes they're touting as temporary solutions until Microsoft gets its act together.
