CVE-2023-29074Network attack vector

Code execution via crafted CATPART file parsing

Published Nov 23, 2023 · Updated Aug 2, 2024

Out-of-bounds write in Autodesk AutoCAD 2021 through 2024 allows attackers to execute code via a crafted CATPART file. The CATPART parser writes beyond a memory boundary while processing attacker-controlled file data; Autodesk has not disclosed the affected routine. An affected application must parse the file, after which exploitation can crash the process, expose sensitive data, or run code in that process.
