CVE-2019-16319 describes a denial-of-service vulnerability in Wireshark versions 3.0.0 through 3.0.3 and 2.6.0 through 2.6.10, specifically within the Gryphon dissector. An attacker could trigger an infinite loop by crafting a malicious network packet with a zero-length message, affecting various Debian and OpenSUSE distributions of Wireshark. This vulnerability is rated as High severity (CVSS 7.5), indicating it can be exploited remotely with low attack complexity and no user interaction, leading to a complete denial of service (system availability impact). While the impact on confidentiality and integrity is none, the ability to halt the application is significant. Currently, there is no evidence of active exploitation, and no public exploit code (Metasploit, Nuclei, ExploitDB) or community discussion has been identified. This suggests a low immediate threat, though the vulnerability has been patched.
