7.0 - 8.9 |
A vulnerability, which if exploited, would directly impact the confidentiality, integrity or availability of user’s data or processing resources. |
Critical |
9.0 - 10 |
A vulnerability, which if exploited, would allow remote execution of malicious code without user action. |
Summary
Applications and Services that utilize versions of PDFTron prior to 9.1.17 may be impacted by Heap-based Buffer Overflow, and Untrusted Pointer Dereference vulnerabilities.
Description
The details of the vulnerabilities are as follows:
1) CVE-2022-27871: Autodesk AutoCAD product suite, Revit, Design Review, 3ds Max, and Navisworks releases using PDFTron prior to 9.1.17 version may be used to write beyond the allocated buffer while parsing PDF files. This vulnerability may be exploited to execute arbitrary code.
2) CVE-2022-27872 : A maliciously crafted PDF file may be used to dereference a pointer for read or write operation while parsing PDF files in Autodesk Navisworks 2022. The vulnerability exists because the application fails to handle a crafted PDF file, which causes an unhandled exception. An attacker can leverage this vulnerability to cause a crash or read sensitive data or execute arbitrary code.

*Note: Product list table contents subject to change.
** Note: Users of Autodesk Advance Steel, Autodesk Civil 3D, and the specialized toolsets of AutoCAD need to install either the AutoCAD product update(s) listed above or a more recent product version. These security fixes are not included in the updates specific to individual toolsets.
Recommendations
Autodesk strongly recommends that users of the affected products listed above apply the available hotfix for their version via the Autodesk Desktop App or the Accounts Portal. As a general best practice, we also recommend that customers only open PDF files from trusted sources.
In addition, users of the 2019, 2020, 2021 and 2022 versions of Autodesk® Advance Steel, Autodesk® Civil 3D®, AutoCAD®, AutoCAD® LT, and AutoCAD-based specialized toolsets listed in the table above should install the latest AutoCAD®, AutoCAD LT 2022 Updates via the Autodesk Desktop App or Accounts Portal. An update is not available for 32bit AutoCAD 2019. Customers using this version should plan to upgrade to 64bit AutoCAD 2019 or a newer AutoCAD version as soon as possible to avoid downtime and potential security vulnerabilities.
Users of Autodesk® Navisworks ® should install the latest 2022 Update 2, which is available via the Autodesk Desktop App or Accounts Portal. This version of Autodesk ® Navisworks ® includes security updates that address the PDF file vulnerabilities. As a general best practice, we also recommend that customers only open PDF files from trusted sources.
Customers using previous versions that no longer qualify for full support should upgrade to a supported version as soon as possible to avoid downtime and potential security vulnerabilities. Visit the Autodesk Knowledge Network for more information about previous version support.
