Report a false positive

Rule Category

FILE-OTHER -- Snort detected traffic targeting vulnerabilities in a file type that does not require enough rule coverage to have its own category.

Alert Message

FILE-OTHER RealNetworks RealPlayer compressed skin overflow attempt

Rule Explanation

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.

CVE

CVE-2004-1094 CVE-2004-0575

Rule Vulnerability

Buffer Overflow

Buffer Overflows occur when a memory location is filled past its expected boundaries. Computer attackers target systems without proper terminating conditions on buffers, which then write the additional information in other locations in memory, overwriting what is there. This could corrupt the data, making the system behave erratically or crash. The new information could include malicious executable code, which might be executed.
