ECMP dissector crash in Wireshark 4.4.0 to 4.4.1 and 4.2.0 to 4.2.8 allows denial of service via packet injection or crafted capture file
A flaw was found in Wireshark's ECMP dissector. This issue occurs when malformed packets are decoded from a pcap file or the network, causing a buffer over-read and resulting in a denial of service.
Отчет
This vulnerability will cause a crash in Wireshark with no other security impact. For this reason, this flaw has been rated with a moderate severity.
Меры по смягчению последствий
If the ECMP 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
