RTSP memory corruption via SETUP use-after-free

Published Jan 12, 2024 · Updated Sep 3, 2024

Heap use-after-free in live555 2023.05.10 allows remote attackers to corrupt RTSP server memory while handling a SETUP request. The public record identifies the SETUP-handling path as the locus but does not disclose which heap object is freed or which later operation reuses it. No authentication or user interaction is required; published evidence does not demonstrate a reliable crash, code execution, or data disclosure consequence.
