A bug was found in libreport which causes that user's changes made to reported data are thrown away. Only the changes to the first file in the list are saved and the rest is discarded. It means that Bugzilla attachments can contain data that user wanted to remove. The affected files are: - backtrace - cmdline (/proc/[pid]/cmdline) - environ (/proc/[pid]/environ) - open_fds (/proc/[pid]/{fd,fdinfo}) - maps (/proc/[pid]/maps) - smaps (/proc/[pid]/smaps) - hostname - remote ("1" if the problem directory was uploaded from another host) - ks.cfg (Anaconda's ks.cfg file) - anaconda-tb The bug has been introduced with libreport-2.0.7 which was released in Fedora 16.
Upstream patch: https://github.com/abrt/libreport/commit/257578a23d1537a2d235aaa2b1488ee4f818e360
The BZ group in question has 10 emails, one of which appears to be a fedoraproject mailing list (no idea how big). The information leaked could be sensitive, e.g. ks.cfg, the command line options and so on. So this gets a CVE and unembargo since the commit is public and explains what is going on as well.
