RE: Wine being targeted for adware
by Eduardo Menezes 16 Jan '09

16 Jan '09

I think a "isolate prefix" option in winecfg (or even winetricks) would be very useful. Undoing symlinks and editing the registry to take out the reference to the root is boring (and I'm not sure only doing this is entirely safe) and this kind of option would make it possible to run untrusted software without worrying. I even ran some malwares in isolated wine prefixes and used diff to see what it did. Learned a lot from this. Anyway, a "nice to have" feature. Best wishes and thanks for this amazing software, 2009/1/14 <wine-devel-request(a)winehq.org> > Date: Wed, 14 Jan 2009 15:07:06 -0500 > From: Nicholas LaRoche <nlaroche(a)vt.edu> > Subject: Re: Wine being targeted for adware > To: Stefan D?singer <stefan(a)codeweavers.com> > Cc: wine-devel(a)winehq.org > Message-ID: <496E45EA.9060603(a)vt.edu> > Content-Type: text/plain; charset=windows-1252; format=flowed > > Stefan D?singer wrote: > >> As long as the facilities exist for keeping an entire wine bottle > >> isolated from other bottles (and ~/) I don't see this being a major > >> issue. > > They don't. > > > > Even if you don't have a drive link pointing out of a bottle, a Windows > app > > running in Wine can still call Linux syscalls(int 0x80).

RFC: fd.o file type association integration
by Damjan Jovanovic 16 Jan '09

16 Jan '09

Hi I've hacked together a little program (attached) that creates freedesktop file type associations (eg. open .dev files with Dev-C++ when you double-click them in a file manager) from what Windows programs do in the registry (#13597). Currently it works well, but has to be run explicitly to refresh the associations. Ideally we'd have something in Wine that automatically refreshes the associations when they change, but since they are done in the registry, what's the way to go here? Do it on every wineboot, or in some permanently running process (explorer?) that monitors the registry for changes? Also what is a good way to invent a MIME type for an extension? Currently for a .ext extension I'm just using application/x-wine-ext. Comments much appreciated. Damjan

WMF Support
by Erich Hoover 16 Jan '09

16 Jan '09

I ran into an issue with WMF files in helping someone get an application to work (Athena Visual Studio) and I worked around it by pre-rendering the application's vector WMF files. I don't currently have the time to resolve the issue, but for when I do I'm curious whether there is a reason that OleLoadPicture* has been implemented manually. It seems that the LGPL "libwmf" has excellent support for both bitmap and vector WMF files (it at least worked for converting the files I had trouble with!), so it seems to me like it would make sense to use this library rather than spinning a separate implementation. Any comments are appreciated. Erich Hoover ehoover(a)mines.edu

This has been discussed before, we cannot rely on IsTextUnicode since it's just a heuristic. MSDN mentions that the character set depends on whether the client called DdeInitializeA or DdeInitializeW, and it can be overridden by setting iCodePage in the CONVCONTEXT structure. This suggests to me that we'll need some form of IPC. -Hans

Wine being targeted for adware
by Jeff Zaroyko 15 Jan '09

15 Jan '09

http://philosecurity.org/2009/01/12/interview-with-an-adware-author In an interesting interview, former adware author Matt Knox mentions that he was able to run his adware client on Wine: S: In your professional opinion, how can people avoid adware? M: Um, run UNIX. S: [ laughs] M: We did actually get the ad client working under Wine on Linux. S: That seems like a bit of a stretch! M: That was a pretty limited market, I'd say.

The wink should have been a hint. I'm happy that Hans got IE 7 working and installed. I also think there is more work to be done before it can be fully used and then there should be patches submitted to implement this either in Wine Gecko or to allow installation of this product in Wine. Again, good job Hans and thank you for the screen shot showing IE7 can work with Wine. James McKenzie
