CVE-2021-43278

Estado: ModificadaAlta (7.8)—

An Out-of-bounds Read vulnerability exists in the OBJ file reading procedure in Open Design Alliance Drawings SDK before 2022.11. The lack of validating the input length can trigger a read past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
