Summary

An integer overflow vulnerability in Ashlar-Vellum Cobalt during VC6 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 an integer overflow before allocating a buffer.

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 VC6 files from untrusted sources. Consider restricting privileges of users who open design files.

Ashlar-Vellum Cobalt VC6 File Parsing Integer Overflow 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 VC6 files. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-25704.
