Stack-based buffer overflow in the CSmil1Parser::testAttributeFailed function in smlparse.cpp for 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 a .SMIL file with a large system-screen-size value.

Heap-based buffer overflow in RealPlayer 10 and earlier, Helix Player before 10.0.4, and RealOne Player v1 and v2 allows remote attackers to execute arbitrary code via a long hostname in a RAM file.

Off-by-one buffer overflow in the processing of tags in Real Metadata Package (RMP) files in RealPlayer 10.5 (6.0.12.1040) and earlier could allow remote attackers to execute arbitrary code via a long tag.

Buffer overflow in InnerMedia DynaZip DUNZIP32.dll file version 5.00.03 and earlier allows remote attackers to execute arbitrary code via a ZIP file containing a file with a long filename, as demonstrated using (1) a .rjs (skin) file in RealPlayer 10 through RealPlayer 10.5 (6.0.12.1053), RealOne Player 1 and 2, (2) the Restore Backup function in CheckMark Software Payroll 2004/2005 3.9.6 and earlier, (3) CheckMark MultiLedger before 7.0.2, (4) dtSearch 6.x and 7.x, (5) mcupdmgr.exe and mghtml.exe in McAfee VirusScan 10 Build 10.0.21 and earlier, (6) IBM Lotus Notes before 6.5.5, and other products. NOTE: it is unclear whether this is the same vulnerability as CVE-2004-0575, although the data manipulations are the same.

Integer overflow in pnen3260.dll in RealPlayer 8 through 10.5 (6.0.12.1040) and earlier, and RealOne Player 1 or 2 on Windows or Mac OS, allows remote attackers to execute arbitrary code via a SMIL file and a .rm movie file with a large length field for the data chunk, which leads to a heap-based buffer overflow.

Stack-based buffer overflow in the HandleAction function in RealPlayer 10.5 (6.0.12.1040) and earlier allows remote attackers to execute arbitrary code via a long ShowPreferences argument.

Directory traversal vulnerability in RealPlayer 10.5 (6.0.12.1040) and earlier allows remote attackers to delete arbitrary files via a Real Metadata Packages (RMP) file with a FILENAME tag containing .. (dot dot) sequences in a filename that ends with a ? (question mark) and an allowed file extension (e.g. .mp3), which bypasses the check for the file extension.
