Doc Text:
A flaw was found in FFmpeg. When processing media streams using the Real-Time Streaming Protocol (RTSP), the client fails to enforce a limit on redirection responses. A malicious or compromised RTSP server can repeatedly redirect requests back to itself or another host, trapping the application in an infinite loop. This issue can result in a Denial of Service (DoS) by consuming excessive system CPU resources and causing the application to hang.

Description OSIDB Bzimport 2026-10-08 17:51:24 UTC
FFmpeg through 9.0.2 contains an infinite loop vulnerability in ff_rtsp_connect() in libavformat/rtsp.c that follows RTSP 3xx redirects without any redirect limit. Attackers controlling an RTSP server can answer every request with a 302 redirect to itself or another server, causing endless reconnects that saturate a CPU core.
