A flaw was found in Wireshark. A remote attacker could exploit a vulnerability in the DCP-ETSI protocol dissector, which is responsible for analyzing network traffic, to cause a crash. This could lead to a denial of service (DoS), making the application unavailable to users.

To reduce the risk of exploitation, users should avoid opening untrusted network capture files or analyzing network traffic from untrusted sources with Wireshark. Additionally, consider running Wireshark in a sandboxed environment to further isolate potential impacts.
