Package: chromium Version: 62.0.3202.89-1 Severity: important Hi! If you download and save a file with Chromium (even in incognito mode), it saves potentially sensitive metadata in a way that's completely unknown to almost all users, even highly technical ones:
user.xdg.referrer.url: https://angband.pl/tmp/ user.xdg.origin.url: https://angband.pl/tmp/20130210_001.jpg This photo is embarassing, but not overwhelmingly so. It also, on its own, appears to include no way to tie to me in particular. There's EXIF but, coming from a sane camera, it has no GPS data or whatever. Yet, once the URL is smuggled, the link to me is obvious, and it's easy to distort the image's story into something that could get someone fired or otherwise publicly shamed (based on typical kitten behaviour). And it can get worse: imagine (werewolf protection) a kiddie porn image, or a secret government file ("Hillary and Donald, sitting in a tree, K.I.S.S.I.N.G.jpg"). In this case, referer is uninteresting, but it can be as bad or worse than the URL itself. This is a concern when the file is copied to any xattr-preserving media, such as an USB stick or a CIFS mount -- or, if your computer itself is imaged/accessed.
