A flaw was found in Wireshark. A local user could be tricked into opening a specially crafted capture file containing Session Description Protocol (SDP) data. Processing this malicious data could lead to a crash in the SDP protocol dissector, resulting in a denial of service for the application.

To mitigate this issue, users should avoid opening untrusted or suspicious capture files with Wireshark. Exercise caution when handling files from unknown sources to prevent accidental application crashes.
