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.

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.

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.

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.

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.

Buffer overflow in common/util/rlstate.cpp in Helix Player 1.0.6 and RealPlayer allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a RuleBook structure with a large number of rule-separator characters that trigger heap memory corruption.

Buffer overflow in the Unescape function in common/util/hxurl.cpp and player/hxclientkit/src/CHXClientSink.cpp in Helix Player 1.0.6 and RealPlayer allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a URL argument containing a % (percent) character that is not followed by two hex digits.

Heap-based buffer overflow in RealNetworks RealPlayer 10, RealPlayer 10.5 6.0.12.1040 through 6.0.12.1741, RealPlayer 11 11.0.0 through 11.0.4, RealPlayer Enterprise, Mac RealPlayer 10 and 10.1, Linux RealPlayer 10, and Helix Player 10.x allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a compressed GIF file, related to gifcodec.cpp and gifimage.cpp.

Stack-based buffer overflow in protocol/rtsp/rtspclnt.cpp in RealNetworks RealPlayer 10; RealPlayer 10.5 6.0.12.1040 through 6.0.12.1741; RealPlayer 11 11.0.x; RealPlayer SP 1.0.0 and 1.0.1; RealPlayer Enterprise; Mac RealPlayer 10, 10.1, 11.0, and 11.0.1; Linux RealPlayer 10, 11.0.0, and 11.0.1; and Helix Player 10.x, 11.0.0, and 11.0.1 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via an ASM RuleBook with a large number of rules, related to an "array overflow."
