Adjacent-network root code execution via MPEG-TS overflow
Published Apr 20, 2023 · Updated Feb 5, 2025
Stack-based buffer overflow in the MPEG-TS parser in Sonos One 70.3-35220 allows remote attackers to execute code as root. The parser copies user-supplied MPEG-TS data into a fixed-length stack buffer without first validating its length, allowing the buffer to overflow. The target must be reachable from the same local network, and no authentication or user interaction is required for root-context code execution.
