      RealPlayer Data Packet Stack Overflow
    ------------------------------------------------------------------------

    SUMMARY

    Lack of proper length validation in RealPlayer's data packet handling
    allows attackers to cause the program to execute arbitrary code using a
    buffer overflow.

    DETAILS

    Vulnerable Systems:
     * RealPlayer version 10.5 (6.0.12.1040-1235) for Windows
     * RealPlayer version 10 for Windows
     * RealOne Player v2 for Windows
     * RealOne Player v1 for Windows
     * RealPlayer version 8 for Windows
     * RealPlayer Enterprise for Windows
     * RealPlayer 10 for Mac
     * RealPlayer 10 (10.0.0 - 5) for Linux
     * Helix Player (10.0.0 - 5) for Linux

    This specific flaw exists in the first data packet contained in a Real
    Media file. By specially crafting a malformed .rm movie file, a direct
    stack overwrite is triggered, and reliable code execution is then
    possible.

    The vulnerability is triggered by setting the application specific length
    field of the [data packet + 1] to 0x80 - 0xFF this will cause a stack
    overflow. The value is sign-extended and passed as the length to memcpy.

    Vendor Status:
    The vendor has issued a patch:
