For those of you who missed it: Microsoft released the associated advisory yesterday, together with a hotfix introducing a new registry key that allows users to control the DLL search path algorithm. For a detailed explanation of the problem we refer to the excellent article on Ars Technica.
For the record: no, AV (anti-virus software) will – in most cases – not protect you from security problems related to this one. And, no, there is no easy patch for this one either.
Wishing you all some sunny summer days,
