CVE-2021-32950

Estado: ModificadaAlta (7.1)—

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.
