JSON

fw_dbus.py in system-config-firewall 1.2.29 and earlier uses the pickle
Python module unsafely during D-Bus communication between the GUI and the
backend, which might allow local users to gain privileges via a crafted
serialized object.

Notes

Author	Note
mdeslaur	This is actually a flaw in the system-config-firewall backend. system-config-printer opens pickles from the backend, but since we don’t ship the backend (system-config-firewall), we’re not affected.
