If a user is tricked to open a malicious file with the affected products, this could lead the application to crash or potentially arbitrary code execution.\n\nSiemens recommends to update to the latest versions and to limit opening of untrusted files from unknown sources in the affected products.\n\nNote:\n\n-   This advisory also covers security vulnerabilities recently disclosed by Open Design Alliance [0]\n\n[0] https://www.opendesign.com/security-advisories"
