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.
