Here are some of the most significant bugs from the past week in the BugBlog:

There is a bug in the server driver (srv.sys) in many different versions of Microsoft Windows. The bug, discovered by ISS X-Force, may let attackers trigger a blue screen of death. Microsoft acknowledges the problem and has some temporary defenses.

There is a bug in the new Mozilla Firefox 1.5.0.5 that interferes with your ability to view streaming video, especially in the Windows Media format and Real Media format. The discussion in Bugzilla says that a fix may be here fairly quickly in the form of a Firefox 1.5.0.6 release.

If you create a new folder in Mac OS X 10.2 through 10.3.9, and then you delete it before you rename it, the parent folder may also get moved into the trash. Apple says this happens if the Finder window is in column view, and then you use Command-delete, or Move to Trash. The first thing to do is go get the parent folder out of the trash. If you don't know how, see Apple's suggestions on what to do. What you don't want to do is empty the trash.
