ZigBee ZCL protocol dissector crash in 4.6.0 to 4.6.8 allows denial of service
A flaw was found in the ZigBee ZCL protocol dissector in Wireshark. This issue occurs when malformed packets are decoded from a pcap file or the network, causing a use-after-free, resulting in a denial of service.
Отчет
This issue will cause a crash in Wireshark with no other security impact. Also, this flaw can only be exploited when malformed packets from a pcap file or the network are processed. Due to these reasons, this vulnerability has been rated with a moderate severity.
Меры по смягчению последствий
If the ZigBee ZCL protocol dissector is not being used, it can be disabled via the "Enabled Protocols" dialog box in the Wireshark GUI application. This will also disable the protocol dissector when using "tshark", the command line tool. See the links below for instructions to disable a protocol in Wireshark, specifically the "Control Protocol Dissection" section and the "disabled_protos" configuration file option. https://www.wireshark.org/docs/wsug_html_chunked/ChCustProtocolDissectionSection.html https://www.wireshark.org/docs/wsug_html_chunked/ChAppFilesConfigurationSection.html
