Description Florian Weimer 2015-04-17 14:45:25 UTC 
It was discovered that the abrt event scripts create a user-readable
copy of a sosreport file in abrt problem directories, and include
excerpts of /var/log/messages selected by the user-controlled process
name, leading to an information disclosure.
