Summary

An Out-of-bounds Read vulnerability exists in the DGN file reading procedure in Open Design Alliance Drawings SDK before 2022.11. Crafted data in a DGN file and lack of verification of input data 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.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Overread Buffers
    An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.
