    "data": "A vulnerability has been identified in NX 1953 Series (All versions \u003c V1973.3700), NX 1980 Series (All versions \u003c V1988), Solid Edge SE2021 (All versions \u003c SE2021MP8). The affected application contains a use-after-free vulnerability while parsing OBJ files. An attacker could leverage this vulnerability to execute code in the context of the current process (ZDI-CAN-13771). This vulnerability allows remote attackers to execute arbitrary code on affected installations of Siemens Solid Edge Viewer. 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 OBJ files. The issue results from the lack of validating the existence of an object prior to performing operations on the object. 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",
