Summary
An out-of-bounds read vulnerability in Ashlar-Vellum Cobalt during AR file parsing allows remote code execution. User interaction is required — the target must open a malicious file or visit a malicious page. The flaw stems from lack of validation of user-supplied data, resulting in a read past the end of an allocated data structure.
Risk Assessment
An attacker can execute arbitrary code in the context of the current process, potentially leading to full compromise of the user's workstation. This is especially relevant in engineering and design environments where CAD files from untrusted sources are opened.
Recommendation
Update Ashlar-Vellum Cobalt to the latest patched version and avoid opening AR files from untrusted sources. Consider restricting privileges of users who open design files.

- CVE-2025-11465High
A use-after-free vulnerability in Ashlar-Vellum Cobalt during CO file parsing allows remote attackers to execute arbitrary code. User interaction is required — the victim must visit a malicious page or open a malicious file. The flaw results from the lack of validating an object's existence before performing operations on it.
- CVE-2025-11464High
A heap-based buffer overflow vulnerability in Ashlar-Vellum Cobalt during CO file parsing allows remote attackers to execute arbitrary code. User interaction is required — the victim must visit a malicious page or open a malicious file. The flaw results from the lack of proper validation of the length of user-supplied data before copying it to a heap-based buffer.

Original NVD description (English source)
Ashlar-Vellum Cobalt AR File Parsing Out-Of-Bounds Read Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Ashlar-Vellum Cobalt. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of AR files. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated data structure. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-25943.
