Remote code execution via out-of-bounds object write
Published Feb 11, 2020 · Updated Aug 4, 2024
Out-of-bounds write in Microsoft ChakraCore before 1.11.16 allows remote attackers to execute code through crafted script content. The scripting engine writes beyond allocated memory while handling attacker-controlled objects; Microsoft has not disclosed the specific function or object operation. In Edge Legacy, exploitation requires a user to open attacker-controlled content, and successful corruption runs code in the user's browser context.
