Affected: Ashlar-Vellum Cobalt, Ashlar-Vellum Cobalt Share, Ashlar-Vellum Xenon, Ashlar-Vellum Argon, Ashlar-Vellum Lithium

In Ashlar-Vellum Cobalt versions prior to v12 SP2 Build (1204.200), the affected application lacks proper validation of user-supplied data when parsing XE files. This could lead to an out-of-bounds write. An attacker could leverage this vulnerability to execute arbitrary code in the context of the current process.
