CVE-2021-32936: Siemens JT2Go DXF File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability
First published: Thu Jun 17 2021(Updated: )
An out-of-bounds write issue exists in the DXF file-recovering procedure in the Drawings SDK (All versions prior to 2022.4) resulting from the lack of proper validation of user-supplied data. This can result in a write past the end of an allocated buffer and allow attackers to cause a denial-of-service condition or execute code in the context of the current process.
