Vulnerability from variot
An issue was discovered in Open Design Alliance Drawings SDK before 2021.12. A memory allocation with excessive size vulnerability exists when reading malformed DGN files, which allows attackers to cause a crash, potentially enabling denial of service (crash, exit, or restart). This vulnerability allows remote attackers to execute arbitrary code on affected installations of Siemens JT2Go. 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 DGN files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. The development kit accesses the data in .dwg and .dgn through a convenient, object-oriented API, and provides functions such as C++ API, support for repairing files, and support for .NET, JAVA, and Python development languages
