Remote code execution via BMP heap overflow
Published Dec 21, 2021 · Updated Aug 4, 2024
Improper input validation in Open Design Alliance Drawings SDK before 2022.12 allows attackers to execute code via a crafted BMP file. The BMP reader writes past an allocated buffer when processing attacker-controlled dimensions or pixel data, producing a heap-based buffer overflow. Exploitation requires a vulnerable process to open the malicious BMP; successful exploitation runs code in that process context, while malformed files can also crash the process.
