Summary
An Out-of-Bounds Read vulnerability exists when reading a DXF file using Open Design Alliance Drawings SDK before 2022.11. The specific issue exists within the parsing of DXF files. Crafted data in a DXF file (an invalid dash counter in line types) 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.
