CVE-2021-32950: Siemens JT2Go DXF File Parsing Out-Of-Bounds Read Information Disclosure Vulnerability

First published: Thu Jun 17 2021(Updated: )

An out-of-bounds read issue exists within the parsing of DXF files 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 read past the end of an allocated buffer and allows attackers to cause a denial-of-service condition or read sensitive information from memory locations.
