Format string vulnerability in the PROFINET/DCP (PN-DCP) dissector in Wireshark

Comment 1 Tomas Hoger 2009-04-03 14:59:03 UTC 
Upstream bug report:
  https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=3382

Upstream SVN commit, fixing multiple format string flaws across wireshark sources:
  trunk: http://anonsvn.wireshark.org/viewvc?view=rev&revision=26652
  trunk-1.0: http://anonsvn.wireshark.org/viewvc?view=rev&revision=27926

Fix should be included in upstream 1.0.7.

Format string demonstrated by the published profinet PoC is caught by fortify source on Red Hat Enterprise Linux 5 and later, reducing impact of the flaw to non-exploitable crash.

Comment 6 Tomas Hoger 2009-05-28 07:27:28 UTC 
Work-around:

Disable affected Profinet dissectors.  This can be done via GUI - Analyze -> Enabled Protocols... and disable all Profinet dissectors (PN-*).

Alternatively, you can list Profinet dissectors in local (~/.wireshark/disabled_protos) or global (/usr/share/wireshark/disabled_protos) disabled_protos configuration file, read by both GNOME Wireshark GUI and text-only tshark:

pn_dcp
pn_mrp
pn_mrrt
pn_ptcp
pn_rt

Refer to Wireshark documentation regarding further details about configuration file format.
