CVE-2021-32938: Siemens JT2Go DWG File Parsing Out-Of-Bounds Read Information Disclosure Vulnerability
First published: Thu Jun 17 2021(Updated: )
Drawings SDK (All versions prior to 2022.4) are vulnerable to an out-of-bounds read due to parsing of DWG files 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.
