libreport: Possible private data leak in Bugzilla bugs opened by ABRT

libreport 2.0.7 before 2.6.3 only saves changes to the first file when editing a crash report, which allows remote attackers to obtain sensitive information via unspecified vectors related to the (1) backtrace, (2) cmdline, (3) environ, (4) open_fds, (5) maps, (6) smaps, (7) hostname, (8) remote, (9) ks.cfg, or (10) anaconda-tb file attachment included in a Red Hat Bugzilla bug report.
