Integer overflow in the AgentX::receive_agentx function in AgentX++ 1.4.16, as used in RealNetworks Helix Server and Helix Mobile Server 11.x through 13.x and other products, allows remote attackers to execute arbitrary code via a request with a crafted payload length.
RealNetworks Helix Server and Helix Mobile Server before 13.0.0 allow remote attackers to cause a denial of service (daemon crash) via an RTSP SETUP request that (1) specifies the / URI or (2) lacks a / character in the URI.
rmserver in RealNetworks Helix Server and Helix Mobile Server before 13.0.0 allows remote attackers to cause a denial of service (daemon exit) via multiple RTSP SET_PARAMETER requests with empty DataConvertBuffer headers.
Multiple buffer overflows in RealNetworks Helix Server and Helix Mobile Server 11.x before 11.1.8 and 12.x before 12.0.1 allow remote attackers to (1) cause a denial of service via three crafted RTSP SETUP commands, or execute arbitrary code via (2) an NTLM authentication request with malformed base64-encoded data, (3) an RTSP DESCRIBE command, or (4) a DataConvertBuffer request.
Heap-based buffer overflow in Real Networks Helix Server and Helix Mobile Server before 11.1.3, and Helix DNA Server 11.0 and 11.1, allows remote attackers to cause a denial of service (application crash) or execute arbitrary code via a DESCRIBE request that contains an invalid LoadTestPassword field.
