It was found that ABRT may have exposed non-public information to Red Hat Bugzilla during crash reporting. A bug in the libreport library caused changes made by a user in files included in a crash report to be discarded. As a result, Red Hat Bugzilla attachments may contain data that was not intended to be made public, including host names, IP addresses, or command line options.
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.
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.
