RISK EVALUATION. Successful exploitation of this vulnerability could allow remote attackers to disclose sensitive information on affected installations of ODA Drawing SDK. 3.
Open Design Alliance's Drawing SDK prior to Version 2024.1 is vulnerable to a use after free attack.
Exploitation of this vulnerability requires the target to visit a malicious page or open a malicious file.
The specific vulnerability exists within the parsing of DWG files.
Crafted data in a DWG file can trigger a use after free attack past the end of an allocated buffer.
An attacker could leverage this vulnerability in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process.
CVE-2023-26495 has been assigned to this vulnerability.
Parsing of DWG files in Open Design Alliance Drawings SDK before 2023.6 lacks proper validation of the length of user-supplied XRecord data prior to copying it to a fixed-length heap-based buffer.
An attacker could leverage this vulnerability to execute code in the context of the current process.
CVE-2023-22669 has been assigned to this vulnerability.
A heap-based buffer overflow exists in the DXF file reading procedure in Open Design Alliance Drawings SDK before 2023.6.
CVE-2023-22670 has been assigned to this vulnerability.
When remote access is required, use more secure methods, such as Virtual Private Networks, recognizing VPNs may have vulnerabilities and should be updated to the most current version available.
