Due to failure in validating the length provided by an attacker-crafted RTPS 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.

CVE-2023-0666 is a heap-based buffer overflow vulnerability identified in Wireshark Foundation's Wireshark software, specifically affecting version 4.0.0 and prior versions up to 4.0.5. The root cause is a failure to properly validate the length field in RTPS (Real-Time Publish-Subscribe) protocol packets. When Wireshark processes a maliciously crafted RTPS packet with an invalid length, it can overflow a heap buffer, leading to memory corruption. This vulnerability is classified under CWE-122 (Heap-based Buffer Overflow). The flaw allows an attacker to potentially execute arbitrary code within the context of the Wireshark process or cause a denial of service by crashing the application. Exploitation requires no privileges and no authentication but does require user interaction in the form of opening a malicious capture file or receiving malicious packets during live capture. The CVSS v3.1 score is 6.5 (medium severity), reflecting network attack vector, low attack complexity, no privileges required, but user interaction needed, and impact primarily on availability. Currently, no public exploits or active exploitation in the wild have been reported. The vulnerability was published on June 7, 2023, and no official patch links are yet provided, indicating that users should monitor for updates from Wireshark Foundation. Given Wireshark's widespread use in network diagnostics and security monitoring, this vulnerability poses a risk to analysts and systems that process untrusted network traffic captures, especially those involving RTPS traffic common in real-time systems and industrial control environments.
