CVE-2021-43280

Estado: ModificadaAlta (7.8)—

A stack-based buffer overflow vulnerability exists in the DWF file reading procedure in Open Design Alliance Drawings SDK before 2022.8. The issue results from the lack of proper validation of the length of user-supplied data before copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
