The May Patch Tuesday crop included two patches, KB 3045171 and KB 3057110, that were implicated in crashes with GDI+ when you used it to create text-outline-based paths on Windows 7 or earlier. As I explained earlier this week, Golden Software users in particular were complaining of an error that looks like this:
Surfer Error / GsDraw error (1): GenericError / Module GsDraw, File Path.cpp, Line 953
At the time, Microsoft acknowledged the problem.
As part of MS15-044 and MS15-051, the original KB 3045171 was an important update -- anyone with Automatic Update turned on got it. We aren’t sure at the moment if KB 3065979, the fix, will also go out as a recommended update, and thus be tagged as Important in Windows Update. It hasn’t started showing up on our machines.
It may be considered a hotfix and, as such, won’t go into the Automatic Update chute. You just have to kind of know that you need it.
