CVE-2025-65086: CWE-787 Out-of-bounds write in Ashlar-Vellum Cobalt
An Out-of-Bounds Write vulnerability is present in Ashlar-Vellum Cobalt, Xenon, Argon, Lithium, and Cobalt Share versions 12.6.1204.216 and prior that could allow an attacker to execute arbitrary code when a specially crafted VC6 file is being parsed.
AI Analysis
Technical Summary
An out-of-bounds write vulnerability (CWE-787) exists in Ashlar-Vellum Cobalt, Xenon, Argon, Lithium, and Cobalt Share versions 12.6.1204.216 and earlier. The vulnerability is triggered by processing a specially crafted VC6 file, potentially enabling arbitrary code execution. The CVSS 4.0 vector indicates the attack requires local access with low complexity, no privileges, and user interaction, but results in high confidentiality, integrity, and availability impact. No patch or official remediation level has been published by the vendor as of the data provided.
Potential Impact
Successful exploitation could allow an attacker to execute arbitrary code on the affected system, compromising confidentiality, integrity, and availability. The attack requires local access and user interaction, which somewhat limits remote exploitation. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a patch is available, users should avoid opening untrusted or suspicious VC6 files and limit local access to trusted users only.
