Lifecycle Timeline
1DescriptionNVD
Due to failure in validating the length provided by an attacker-crafted IEEE-C37.118 packet, Wireshark version 4.0.5 and prior, by default, is susceptible to a heap-based buffer overflow, and possibly code execution in the context of the process running Wireshark.
AnalysisAI
Due to failure in validating the length provided by an attacker-crafted IEEE-C37.118 packet, Wireshark version 4.0.5 and prior, by default, is susceptible to a heap-based buffer overflow, and. Rated medium severity (CVSS 6.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
Technical ContextAI
This vulnerability is classified as Out-of-bounds Read (CWE-125), which allows attackers to read data from memory outside the intended buffer boundaries. Due to failure in validating the length provided by an attacker-crafted IEEE-C37.118 packet, Wireshark version 4.0.5 and prior, by default, is susceptible to a heap-based buffer overflow, and possibly code execution in the context of the process running Wireshark. Affected products include: Wireshark, Debian Debian Linux. Version information: version 4.0.5.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Validate array indices and buffer lengths. Use memory-safe languages. Enable AddressSanitizer during testing.
