Doc Text:
A denial of service vulnerability was found in Wireshark due to insufficient validation of user-supplied input in the CBOR protocol dissector. This issue could allow a remote attacker to inject a malformed packet onto the wire or persuade someone to read a corrupted packet trace file. The issue manifests as an uncontrolled recursion loop leading to a stack overflow, resulting in Wireshark crashing.
