Summary
This host is installed with Wireshark and is prone to multiple denial of service vulnerabilities.
Insight
Insight
Multiple flaws are due to, - The 'logcat_dump_text' function in 'wiretap/logcat.c' in the Android Logcat file parser does not properly handle a lack of \0 termination. - The 'detect_version' function in 'wiretap/logcat.c' in the Android Logcat file parser does not check the length of the payload. - The 'fragment_add_work' function in 'epan/reassemble.c' in the packet-reassembly feature does not properly determine the defragmentation state in a case of an insufficient snapshot length. - 'epan/dissectors/packet-websocket.c' in the WebSocket dissector uses a recursive algorithm, which can result in a consumption of CPU resources. - The 'dissect_lbmr_pser' function in 'epan/dissectors/packet-lbmr.c' in the LBMR dissector does not properly track the current offset and does not reject a zero length.
