It seems like my previous topic has magically disappeared... Or on hold pending moderation.

XnView MP has DEP/ASLR enabled, which is great! Would it be possible to enable /guard:cf as well? It is supported in Visual Studio 2017.

Not everything that quacks like a JPEG is just a JPEG; might be a fancy ROP gadget disguised as an image.

/GUARD:CF, similar to the -fcf-protection (GCC) and CFI (CLang) helps to prevent some of those.
