Memory corruption via freed address-info reuse
Published Aug 10, 2021 · Updated Aug 4, 2024
Use-after-free in net_bind() in OwnTone 28.1 and earlier allows attackers to corrupt memory during network service binding. The function frees the getaddrinfo() result and then passes ptr->ai_addr from that freed list to getsockname() before reading the same storage. The defect occurs while OwnTone creates a listening socket; public records establish invalid memory access but do not document attacker-controlled input or a demonstrated outcome beyond memory corruption.
