The vulnerability could corrupt memory in a way that enables an attacker to execute arbitrary code in the context of the current user. To exploit the vulnerability, an attacker would need to convince a user to open a specially crafted document containing TTS content invoked through a scripting language. The update address the vulnerability by modifying how the system handles objects in memory.
