Vulnerability from variot

A stack-based buffer overflow vulnerability in Delta Electronics DOPSoft Version 4.00.11 and prior may be exploited by processing a specially crafted project file, which may allow an attacker to execute arbitrary code. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the parsing of TBK files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. DOPSoft is a human-machine interface (HMI) programming software launched by Delta Electronics.

A stack buffer overflow vulnerability exists in DOPSoft 4.00.11 and earlier versions. Pillow is a Python-based image processing library. There is currently no information about this vulnerability, please feel free to follow CNNVD or manufacturer announcements
