+++ This bug was initially created as a clone of Bug #803515 +++

This bug is for the changes required to the installer to protect against more dll hijacking see bug 792106 comment 93 onwards relating to cryptbase.dll

I'm splitting this out from bug 803515 to allow better tracking, as bug 803515 has already landed the dwmapi.dll parts.

The cryptbase.dll is currently wontfix for gecko 17 as per bug 792106 comment 125

The fix

I followed the tests script at https://bugzilla.mozilla.org/show_bug.cgi?id=792106#c112, and on Windows 7 64-bit, running my own build of 32-bit debug Thunderbird, none of the libraries the installer required, that were not in the KnownDLLs list, were vulnerable to the DLL hijack.

ESR 10 fix

[Triage Comment]
Ok, self-rs own patch as I realised Irving is away until next week and we need to get this landed before the release - this was formed in exactly the same way as the other executable updates that we've done, and can be verified by compilation/test of the builds. The functional changes were taken from the changes landed by Firefox.

I'll get Irving to verify this fully on Monday before the release, but I'm confident that it is fine.
