CVE-2026-104074

NVD: Coturn 4.10.0 contains an uninitialized memory disclosure vulnerability that allows remote unauthenticated attackers to leak stack memory contents by sending a TURN Allocate request without credentials. NVD: Attackers can exploit the stun_init_error_response_common_str() function in src/client/ns_turn_msg.c, which fails to zero-initialize the avalue buffer before computing its length with strlen() and copying leaked stack bytes into the ERROR-CODE reason phrase...
