Wireshark

Wireshark is a ubiquitously deployed packet-analysis and network-protocol inspection tool that occupies a critical role in network diagnostics, security monitoring, and forensic investigation across enterprises and security operations worldwide. Despite its concentrated product portfolio, the volume and prominence of its vulnerabilities reflect its deep penetration into network infrastructure and its position as a trusted application in high-value defensive workflows. The vendor's disclosures recur around improper input validation, buffer-boundary violations, and infinite-loop conditions—characteristic of a parser-heavy application that must gracefully handle untrusted network traffic in an enormous variety of protocol formats and edge cases. While individual severity and exploitation tendencies vary, defenders should treat Wireshark updates as routine and broadly applicable maintenance, particularly for instances that process untrusted network capture files or live traffic; current exploitation activity, severity distribution, and exposure counts are shown alongside this summary.
