CVE-2023-40222: Ashlar-Vellum Cobalt, Xenon, Argon, Lithium Heap-based Buffer Overflow
First published: Tue Feb 04 2025(Updated: )
In Ashlar-Vellum Cobalt versions prior to v12 SP2 Build (1204.200), the affected application lacks proper validation of user-supplied data when parsing CO files. This could lead to a heap-based buffer overflow. An attacker could leverage this vulnerability to execute arbitrary code in the context of the current process.
