A use-after-free issue exists in the DGN file-reading procedure 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 memory corruption or arbitrary code execution, allowing attackers to cause a denial-of-service condition or execute code in the context of the current process.
