CVE-2021-25360Network attack vector

Code execution via libswmfextractor buffer overflow

Published Apr 9, 2021 · Updated Aug 3, 2024

Improper input validation in Samsung Mobile Devices Q(10.0) allows remote attackers to execute code in the mediaextractor process. The libswmfextractor library accepts input without the bounds validation needed to prevent a buffer overflow in mediaextractor. Published scoring requires no privileges or user interaction but rates attack complexity high; successful exploitation runs code in mediaextractor.
