CVE-2022-34275

Code execution via PCB parser out-of-bounds write

Published Jul 12, 2022 · Updated Aug 3, 2024

Out-of-bounds write in Siemens PADS Standard/Plus Viewer all versions allows attackers to execute code through a crafted PCB file. The PCB file decoder applies an improper bounds check and writes beyond the end of an allocated structure while parsing malformed file data. Exploitation requires a user to open the malicious file and runs attacker-supplied code with the privileges of the viewing process.
