There wont be a Patch Day this month after all. Microsoft has cancelled plans to roll out a solitary bulletin with patches for a Windows flaw, citing an unknown "quality issue."
The software giant had previously announced that a single "critical" bulletin would cover a vulnerability that could be ripe for exploitation by a worm. During last-minute testing, however, Microsoft researchers flagged some problems with the update.
"Late in the testing process, Microsoft encountered a quality issue that necessitated ... additional testing and development [of the update] before it is released," a Microsoft spokesperson said.
