CVE-2022-34277

Code execution via out-of-bounds PCB file read

Published Jul 12, 2022 · Updated Aug 3, 2024

Out-of-bounds read in all versions of Siemens PADS Standard/Plus Viewer allows attackers to execute code via a crafted PCB file. The PCB parser reads past the end of an allocated buffer because file-controlled bounds are not adequately validated. Execution requires a user to open the malicious file and occurs with the Windows viewer process's privileges.
