Description Florian Weimer 2015-04-22 18:20:27 UTC

It was discovered that the abrt-dbus D-Bus service does not properly
check the validity of the problem directory argument in the
ChownProblemDir, DeleteElement, and DeleteProblem methods.  A local
attacker could use this flaw take ownership of arbitrary files and
directories, or to delete files and directories as the root user.
