CVE-2022-24049: Sonos s1 stack-based buffer overflow vulnerability

Sonos · S1

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Sonos One Speaker prior to 3.4.1 (S2 systems) and 11.2.13 build 57923290 (S1 systems). Authentication is not required to exploit this vulnerability. The specific flaw exists within the ALAC audio codec. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-15798.
