Vulnerabilities in the Autodesk® AutoCAD Products
Autodesk ID: ADSK-SA-2019-0001 Product, Service, Component: Autodesk® AutoCAD Impact: Deserialization of Untrusted Data, Heap Overflow, Use After Free Severity: High Original Publish: 14/02/2019 Last Revised: 14/02/2019
CVSS 3.0 Score
0.1 - 3.9
A vulnerability where scope and impact of exploitation is restricted and the ability to exploit is extremely difficult.
4.0 - 6.9
A vulnerability where exploitation is mitigated by factors such as difficulty to exploit, default configuration or ease of identification.
7.0 - 8.9
A vulnerability, which if exploited, would directly impact the confidentiality, integrity or availability of user’s data or processing resources.
9.0 - 10
A vulnerability, which if exploited, would allow remote execution of malicious code without user action.
Multiple Autodesk products have been affected by heap overflow, use-after-free and deserialization vulnerabilities.
The details of the vulnerabilities are as follows:
CVE-2019-7358: An attacker may convince a victim to open a malicious DXF file that may cause a heap overflow which may result in code execution.
CVE-2019-7359: An attacker may convince a victim to open a malicious DXF file with too many cell margins populating an AcCellMargin object and may cause a heap overflow which may result in code execution.
CVE-2019-7360: An attacker may convince a victim to open a malicious DXF file that may trigger a use-after-free vulnerability which may result in code execution.
CVE-2019-7361: An attacker may convince a victim to open a malicious action micro (.actm) file that has serialized data, which may trigger a code execution.
We would like to thank Tim Carrington from MWR Infosecurity for reporting CVE-2019-7361.
