CVE-2011-2520
Published: 21 July 2011
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. |
