Description Florian Weimer 2015-04-22 18:11:37 UTC

It was discovered that the abrt-dbus D-Bus service contains several
directory traversal flaws related to the NewProblem, GetInfo and
SetElement methods.  Local attackers could use these flaws to read and
write arbitrary files as the root user, or take ownership of arbitrary
files and directories.
