| Severity | CVSS Score | Impact |
|---|---|---|
| Low | 0.1 - 3.9 | A vulnerability where scope and impact of exploitation is restricted and the ability to exploit is extremely difficult. |
| Medium | 4.0 - 6.9 | A vulnerability where exploitation is mitigated by factors such as difficulty to exploit, default configuration or ease of identification. |
| High | 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. |
Applications and Services that utilize versions of PDFTron prior to 9.0.7 may be impacted by out-of-bound read and memory corruption vulnerabilities.
The details of the vulnerabilities are as follows:
CVE-2021- 40160: PDFTron prior to 9.0.7 version may be forced to read beyond allocated boundaries when parsing a maliciously crafted PDF file. This vulnerability can be exploited to execute arbitrary code.
CVE-2021- 40161: A Memory Corruption vulnerability may lead to code execution through maliciously crafted DLL files through PDFTron earlier than 9.0.7 version.
CVE-2022-25795: A maliciously crafted PDF file can be used to dereference for a write beyond the allocated buffer while parsing PDFTron files. The vulnerability exists because the application fails to handle a crafted PDFTron file, which causes an unhandled exception. An attacker can leverage this vulnerability to execute arbitrary code.
CVE-2022-27527: A Memory Corruption vulnerability may lead to code execution through maliciously crafted DLL files. It was fixed in PDFTron earlier than 9.0.7 version in Autodesk Navisworks 2022, and 2020.
