BC4 binaries: DEP and ASLR?

[Zoë]

We do have plenty of bugs, but it let me catch the fact that we weren't actually shipping patch.exe in the installer, so it was a good thing to look into.

The next release will have all of the DLLs and EXEs digitally signed, with version information, and with DEP and ASLR protection enabled. The only exceptions are no ASLR for pdftotext.exe and patch.exe, because they're compiled by third parties in a way that doesn't support it.

Thanks for the feedback and audit.

We'll work on enhancing the others, too.

Hi Scooter-Team,

in this thread I suggested to improve tne security of BC binaries:

I'm happy to see that a check of the new BC4 files shows some progress concerning this topic:

Executable name DEP protection  ASLR protection
7zxa.dll        NO              NO
BComp.com       NO              NO
BComp.exe       NO              NO
BCompare.exe    yes             yes
BCShellEx.dll   yes             yes
BCShellEx64.dll NO              NO
BCUnRar.dll     NO              NO
unins000.exe    NO              NO

At least the main files are protected now, thank you

I don't know if the other files could get the protection, too.
But maybe other bugs/problems have higher priotity ...
