CVE-2022-24049Network attack vector

Root code execution via unchecked ALAC frame length

Published Feb 18, 2022 · Updated Aug 3, 2024

Stack-based buffer overflow in Sonos One before 13.4.1 S2 or 11.2.13 build 57923290 S1 allows remote attackers to execute code. The ALAC frame parser copies user-supplied data into a stack buffer without validating its declared length, allowing the buffer to overflow. No authentication or user interaction is required, and successful exploitation runs attacker-controlled code as root.
