RtspServer allows remote attackers to cause a denial of service (daemon hang or restart) via a negative integer in the RTSP Content-Length header.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.19%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
