Description
A heap-based buffer overflow was found in Wireshark's NetScreen file parser. This issue may allow local arbitrary code execution via a crafted capture file.

Wireshark is not an application that runs with elevated privileges, limiting the exploitability and impact of this issue to the user's context. Therefore, the severity score is set to Moderate.
