RealNetworks RealPlayer 10.1.0.3114 and earlier, and Helix Player 1.0.6.778 on Fedora Core 6 (FC6) and possibly other platforms, allow user-assisted remote attackers to cause a denial of service (application crash) via a malformed .au file that triggers a divide-by-zero error.

Heap-based buffer overflow in the RTSP service in Helix DNA Server before 11.1.4 allows remote attackers to execute arbitrary code via an RSTP command containing multiple Require headers.

Stack-based buffer overflow in the SmilTimeValue::parseWallClockValue function in smlprstime.cpp in RealNetworks RealPlayer 10, 10.1, and possibly 10.5, RealOne Player, RealPlayer Enterprise, and Helix Player 10.5-GOLD and 10.0.5 through 10.0.8, allows remote attackers to execute arbitrary code via an SMIL (SMIL2) file with a long wallclock value.

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.

Heap-based buffer overflow in RealNetworks Helix DNA Server 10.0 and 11.0 allows remote attackers to execute arbitrary code via (1) a long User-Agent HTTP header in the RTSP service and (2) unspecified vectors involving the "parsing of HTTP URL schemes".

Buffer overflow in swfformat.dll in multiple RealNetworks products and versions including RealPlayer 10.x, RealOne Player, Rhapsody 3, and Helix Player allows remote attackers to execute arbitrary code via a crafted SWF (Flash) file with (1) a size value that is less than the actual size, or (2) other unspecified manipulations.

Heap-based buffer overflow in the embedded player in multiple RealNetworks products and versions including RealPlayer 10.x, RealOne Player, and Helix Player allows remote malicious servers to cause a denial of service (crash) and possibly execute arbitrary code via a chunked Transfer-Encoding HTTP response in which either (1) the chunk header length is specified as -1, (2) the chunk header with a length that is less than the actual amount of sent data, or (3) a missing chunk header.

Integer overflow in RealNetworks RealPlayer 8, 10, and 10.5, RealOne Player 1 and 2, and Helix Player 10.0.0 allows remote attackers to execute arbitrary code via an .rm movie file with a large value in the length field of the first data packet, which leads to a stack-based buffer overflow, a different vulnerability than CVE-2004-1481.

Format string vulnerability in Real HelixPlayer and RealPlayer 10 allows remote attackers to execute arbitrary code via the (1) image handle or (2) timeformat attribute in a RealPix (.rp) or RealText (.rt) file.

Heap-based buffer overflow in RealNetworks RealPlayer 10.5 (6.0.12.1056 and earlier), 10, 8, and RealOne Player V2 and V1, allows remote attackers to execute arbitrary code via .WAV files.
