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.

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.

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.

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.

Heap-based buffer overflow in the NTLM authentication functionality in RealNetworks Helix Server and Helix Mobile Server 11.x, 12.x, and 13.x allows remote attackers to have an unspecified impact via invalid base64-encoded data.

Stack-based buffer 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 unspecified vectors.

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.

Format string vulnerability 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 vectors related to the x-wap-profile HTTP header.

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.

Buffer overflow in rn5auth.dll in RealNetworks Helix Server and Helix Mobile Server 14.x before 14.3.x allows remote attackers to execute arbitrary code via crafted authentication credentials.

RealNetworks Helix Server and Helix Mobile Server 14.x before 14.3.x store passwords in cleartext under adm_b_db\users\, which allows local users to obtain sensitive information by reading a database.

Multiple cross-site scripting (XSS) vulnerabilities in RealNetworks Helix Server and Helix Mobile Server 14.x before 14.3.x allow remote attackers to inject arbitrary web script or HTML via unspecified vectors.

Cross-site request forgery (CSRF) vulnerability in RealNetworks Helix Server and Helix Mobile Server 14.x before 14.3.x allows remote attackers to hijack the authentication of administrators for requests that cause a denial of service (stack consumption and daemon crash) via a malformed URL.

master.exe in the SNMP Master Agent in RealNetworks Helix Server and Helix Mobile Server 14.x before 14.3.x allows remote attackers to cause a denial of service (daemon crash) by establishing and closing a port-705 TCP connection, a different vulnerability than CVE-2012-1923.

master.exe in the SNMP Master Agent in RealNetworks Helix Server and Helix Mobile Server 14.x before 14.3.x allows remote attackers to cause a denial of service (unhandled exception and daemon crash) via a crafted Open-PDU request that triggers incorrect DisplayString processing, a different vulnerability than CVE-2012-1923.
