Integer overflow in DUNZIP32.DLL for Microsoft Windows XP, Windows XP 64-bit Edition, Windows Server 2003, and Windows Server 2003 64-bit Edition allows remote attackers to execute arbitrary code via compressed (zipped) folders that involve an "unchecked buffer" and improper length validation.

  • Exploit crafts a ZIP file with an oversized filename field (0x8000 bytes) in both the local file header and central directory header to trigger the buffer overflow in Compressed Folders / DUNZIP32.DLL.
  • Malicious ZIP files exploiting this vulnerability will have a FilenameLength field set to an abnormally large value (e.g. 0x8000) in the local file header (signature 0x04034B50) or central directory header (signature 0x02014B50).
  • Attack vector for GetRight is delivery of a malicious .grs skin file; monitor for GetRight loading remotely-sourced .grs files that trigger DUNZIP32.DLL processing.
  • Attack vector for RealPlayer is delivery of a malicious .rjs skin file; monitor for RealPlayer loading remotely-sourced .rjs files that trigger DUNZIP32.DLL processing.
  • Detect exploit attempts against explorer.exe: the PoC instructs attackers to attach a debugger to explorer.exe and search its memory for shellcode after opening the malicious ZIP as a folder.
  • ·The NVD source documents CVE-2004-1094 (InnerMedia DynaZip DUNZIP32.dll), which NVD itself notes may or may not be the same vulnerability as CVE-2004-0575 (MS04-034, Windows Compressed Folders). IOCs from the DUNZIP32.dll advisory should be applied cautiously when targeting only CVE-2004-0575.
  • ·The MS04-034 PoC exploit (exploit-db 640) was tested only on Windows XP SP0 Spanish/English; offsets embedded in the shellcode are platform-specific and must be recalculated for other targets.
  • ·The GetRight exploit (exploit-db 677) targets DUNZIP32.DLL version 4.0.0.3, which is an older version than the 5.00.03 referenced in the CVE-2004-1094 advisory; version-specific detection rules should account for both.
