It's not because the flaw is unpatchable, but because fixing the vulnerability requires a significant software rewrite, which indicates that the company will need to issue an all-new version of Skype rather than just a patch. The vulnerability has been discovered and reported to Microsoft by security researcher Stefan Kanthak and resides in Skype's update installer, which is susceptible to Dynamic Link Libraries (DLL) hijacking.
