CVE-2021-45860Public exploit

Application crash via AUPR header size overflow

Published Mar 1, 2022 · Updated Aug 4, 2024

Integer overflow in DTSStreamReader in tsMuxer Project tsMuxer git-2678966 allows local users to crash it via a crafted DTS file. The findFrame() bounds check adds an attacker-controlled AUPR header size to the buffer pointer, allowing pointer wraparound to make an undersized buffer appear valid. Exploitation requires a user to process the file locally and interrupts only that tsMuxer process, with no reported data disclosure or modification.
