The vulnerability exists due to a boundary error when trying to decrypt CMS messages encrypted using password based encryption. A remote attacker can trigger an out-of-bounds write and execute arbitrary code on the target system.

A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
