CVE-2021-38402 (GCVE-0-2021-38402)

Vulnerability from cvelistv5 – Published: 2021-09-17 18:54 – Updated: 2025-04-23 19:27

Title

Delta Electronics DOPSoft 2 Stack-Based Buffer Overflow

Summary

Delta Electronic DOPSoft 2 (Version 2.00.07 and prior) lacks proper validation of user-supplied data when parsing specific project files. This could lead to a stack-based buffer overflow while trying to copy to a buffer during font string handling. An attacker could leverage this vulnerability to execute code in the context of the current process.
