Format string vulnerability in the PROFINET/DCP (PN-DCP) dissector in Wireshark
1.0.6 and earlier allows remote attackers to execute arbitrary code via a
PN-DCP packet with format string specifiers in the station name. NOTE: some of
these details are obtained from third party information.
Upstream bug report:
Upstream SVN commit, fixing multiple format string flaws across wireshark sources:
Fix should be included in upstream 1.0.7.
