Adobe has issued several out-of-band updates this year for Reader. Adobe last released an emergency Reader update in late June when it moved up the already-scheduled July 13 fixes by two weeks to deal with a bug hackers were already exploiting. It also rushed a Reader fix to customers in February .
The push to come up with a fix for the latest Reader zero-day will not affect work on the next major upgrade to the program, Adobe said today. Reader 10, which should ship for Windows before the end of the year, is to include "sandboxing" technology to isolate malicious PDF documents -- such as the kind that might leverage Miller's vulnerability -- so that they can't infect the PC.
