Sharkd utility crash 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. A heap-based buffer overflow in the sharkd utility can cause the application to crash, resulting in a Denial of Service (DoS). An attacker could exploit this vulnerability by convincing a user to process specially crafted input.
Меры по смягчению последствий
To mitigate this flaw, restrict access to the sharkd daemon or remove the package if it is not required:
- Terminate running sharkd processes if daemonized packet analysis is not required: killall sharkd
- If sharkd must be run over a network socket, bind it only to localhost or restrict incoming network traffic to trusted hosts using firewall rules: firewall-cmd --remove-port=/tcp --permanent firewall-cmd --reload Warning: Reloading firewall rules may temporarily disrupt active network connections.
- If Wireshark command-line utilities are not necessary, remove the package providing the tool: dnf remove wireshark-cli Caveat: Removing wireshark-cli will remove related packet capture and dissection tools such as tshark.
