Heap-based buffer overflow in the CGIFCodec::GetPacketBuffer function in datatype/image/gif/common/gifcodec.cpp 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, 10.1, and 11.0; Linux RealPlayer 10; and Helix Player 10.x allows remote attackers to execute arbitrary code via a GIF file with crafted chunk sizes that trigger improper memory allocation.

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 execute arbitrary code via a file with invalid ASMRuleBook structures that trigger heap memory corruption.

Stack-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 user-assisted remote attackers to execute arbitrary code via a malformed .RJS skin file that contains a web.xmb file with crafted length values.

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 allow remote attackers to have an unspecified impact via a crafted media file that uses HTTP chunked transfer coding, related to an "overflow."

Unspecified vulnerability in RealNetworks RealPlayer Enterprise, RealPlayer 10, and RealPlayer 10.5 before build 6.0.12.1675 has unknown impact and attack vectors, probably related to accessing local files, aka a "Local resource reference vulnerability."

Stack-based buffer overflow in a certain ActiveX control in rjbdll.dll in RealNetworks RealPlayer Enterprise, RealPlayer 10, and RealPlayer 10.5 before build 6.0.12.1675 allows remote attackers to execute arbitrary code by importing a file into a media library and then deleting this file.

Heap-based buffer overflow in the Shockwave Flash (SWF) frame handling in RealNetworks RealPlayer 10.5 Build 6.0.12.1483 might allow remote attackers to execute arbitrary code via a crafted SWF file.

The RealAudioObjects.RealAudio ActiveX control in rmoc3260.dll in RealNetworks RealPlayer Enterprise, RealPlayer 10, RealPlayer 10.5 before build 6.0.12.1675, and RealPlayer 11 before 11.0.3 build 6.0.14.806 does not properly manage memory for the (1) Console or (2) Controls property, which allows remote attackers to execute arbitrary code or cause a denial of service (browser crash) via a series of assignments of long string values, which triggers an overwrite of freed heap memory.

Heap-based buffer overflow in RealNetworks RealPlayer 8, 10, 10.1, and possibly 10.5; RealOne Player 1 and 2; and RealPlayer Enterprise allows remote attackers to execute arbitrary code via a crafted RM file.

Integer overflow in RealNetworks RealPlayer 10 and 10.5, RealOne Player 1, and RealPlayer Enterprise for Windows allows remote attackers to execute arbitrary code via a crafted Lyrics3 2.00 tag in an MP3 file, resulting in a heap-based buffer overflow.
