18
FAUCET Score

CVE-2023-0668 is a heap-based buffer overflow vulnerability affecting Wireshark versions 4.0.5 and prior, specifically when processing attacker-crafted IEEE-C37.118 packets. This flaw stems from a failure to validate packet length, potentially leading to denial of service or arbitrary code execution within the Wireshark process. Rated as MEDIUM severity (CVSS 6.5), it requires user interaction (UI:R) and can be exploited remotely over the network (AV:N). There is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion surrounding this vulnerability.
