CVE-2023-0668: Debian Linux

Medium severity, CVSS 6.5. EPSS: 2.3% chance of exploitation in the next 30 days.

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

• Debian Debian Linux: version 12.0 only
• Wireshark Wireshark: from 3.6.0, before 3.6.14 (fixed in 3.6.14); from 4.0.0, before 4.0.6 (fixed in 4.0.6)
