CVE-2010-4596
Stack-based buffer overflow in RealNetworks Helix Server 12.x, 13.x, and 14.x before 14.2, and Helix Mobile Server 12.x, 13.x, and 14.x before 14.2, allows remote attackers to execute arbitrary code via a long string in an RTSP request.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.03%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
