A remote code execution vulnerability exists when the Microsoft Speech API (SAPI) improperly handles text-to-speech (TTS) input. 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.
