The affected software contains a buffer overflow vulnerability while handling certain files that could allow a local attacker to trigger a denial-of-service condition or potentially lead to remote code execution. Multiple Siemens products contain a classic buffer overflow vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. Siemens SIMATIC PCS 7 is a set of process control system of Germany Siemens (Siemens) company. SIMATIC STEP 7 V5.X is the classic engineering software for configuring and programming SIMATIC S7-300/S7-400/C7/WinAC controllers. STARTER is the drive engineering tool for parameterization and commissioning. Pillow is a Python-based image processing library. \nThere is currently no information about this vulnerability, please feel free to follow CNNVD or manufacturer announcements",
