Service interruption via uninitialized pointer access
Published Dec 20, 2021 · Updated Aug 4, 2024
Uninitialized-pointer access in Fuji Electric V-Server Lite and Tellus Lite V-Simulator before 4.0.12.0 allows attackers to crash the process. The affected code accesses a pointer before initialization and consequently reads from or writes to unintended memory; the parser, file type, and function are undisclosed. Exploitation requires user interaction with attacker-controlled input, and the published record establishes service interruption but not code execution.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
