## Technical details

An Out-of-Bounds Read (CWE-125) exists in multiple Ashlar-Vellum products, including Cobalt, Xenon, Argon, Lithium, and Cobalt Share. The vulnerability is triggered during the parsing of specially crafted VC6 files. An attacker can exploit this by convincing a user to open a malicious file, leading to memory corruption. This can result in the disclosure of sensitive memory contents or the execution of arbitrary code in the context of the current user. The vendor has released build 12.6.1204.217 to address this issue.

## 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
