## Technical details

An out-of-bounds write vulnerability (CWE-787) exists in Ashlar-Vellum Cobalt, Xenon, Argon, Lithium, and Cobalt Share. The flaw is triggered when the application processes a specially crafted file, leading to memory corruption. An attacker can exploit this by convincing a user to open a malicious file, potentially achieving arbitrary code execution or sensitive information disclosure in the context of the current user. The vulnerability is addressed in build 12.6.1204.217 and later.

## Affected products

- Ashlar-Vellum Cobalt <= 12.6.1204.216
- Ashlar-Vellum Xenon <= 12.6.1204.216
- Ashlar-Vellum Argon <= 12.6.1204.216
- Ashlar-Vellum Lithium <= 12.6.1204.216
- Ashlar-Vellum Cobalt Share <= 12.6.1204.216
