OPENOFFICE BUG ALLOWS HACKERS TO SIGNED MAC OS X

I also tried applying this on Mac OS X Mavericks (which also uses file 5.04) by dropping the file into /usr/share/file/magic and recompiling the magic database ( sudo file -c). etc/magic, 38: Warning: MIME type `application/' truncated 64Īpplication/ charset=binary etc/magic, 36: Warning: MIME type `application/' truncated 64 etc/magic, 34: Warning: MIME type `application/.' truncated 64 Is there anyway to enforce the content type value when it's known? In this case we are using internally generated files, so the files themselves are not tainted (there may be tainted data within the file but that's a completely separate issue). If I change the content type before the file is assigned it ignores the setting because it's assigned in the IO Adapter. I can change the content_type after the file is assigned, but it's already been sent to S3 and that doesn't change the record on S3. Previously Paperclip assigned the right content type ( application/) which is also what was sent to S3. Paperclip now uploads to S3 with application/zip and then the download link through the browser causes them to be saved with a.

(Which might provide more direction/support for your mimemagic change.)įor us this was not an issue with Paperclip 3.2, but became an issue upgrading to 4.2.

This SF post describes adding rules derived from the Ubuntu utilities. Or, at least it depends on the system and what rules are added (which is I think what you said above). I don't think that the magic gem will work any better than file because it appears to be a core issue with libmagic. I saw those comments on the mimemagic tracker which is basically a non-starter.

I started a branch that works if you have a version of MimeMagic with my patch applied to the input d7a17eb I also attempted to compile my own file-formatted mime magic database (.mgc file) that we could include and point to with -m, but as far as I can tell those files are not compatible across different versions of file, so that doesn't work. MimeMagic also doesn't do the heuristic for text/plain vs application/octet-stream that file does, but a) that doesn't seem so hard and b) we can always fall back to file for that. Unfortunately they don't detect xslx correctly. It's pure ruby - he's got his own process for converting their data into ruby code. I found, which uses the dataset the people use for e.g., gnome.

Use a gem like magic which uses FFI to directly link to libmagic (what file uses), but enhance it to compile libmagic at install time.My outsider view is that it's not great for paperclip to assume I have an installed executable of a certain version if at all avoidable. Unfortunately it's a pain to upgrade that for heroku-specific reasons. There's a more recent version of file than what's on heroku that correctly determines the mime-type for these files. FYI I did a little more research on this.
