USB HID protocol dissector infinite loop and memory leak in 4.6.0 to 4.6.8 and 4.4.0 to 4.4.18 allows denial of service
A flaw was found in Wireshark. This vulnerability allows an attacker to cause a Denial of Service (DoS) by convincing a user to open a specially crafted packet capture file containing malformed Universal Serial Bus Human Interface Device (USB HID) traffic. When processing the malformed data, the USB HID protocol dissector enters an infinite loop and leaks memory, leading to excessive resource consumption and application unresponsiveness.
Меры по смягчению последствий
Disable the USB HID protocol dissector when USB HID traffic inspection is not required, or avoid processing capture files from untrusted sources. To disable the protocol dissector in TShark:
To disable the dissector persistently in Wireshark:
- Open the GUI and select Analyze -> Enabled Protocols.
- Locate "USB HID" (filter name usbhid) and deselect it.
Alternatively, append
usbhidto the disabled protocols file located at~/.config/wireshark/disabled_protos. Caveat: Disabling the USB HID dissector prevents packet decoders from parsing USB HID payload structures, displaying affected packets only as raw USB data.
