Detection & IOCsextracted from sources · hover to see the quote
- →Crash occurs in MSVCR80!memcpy due to an invalid source buffer, indicative of a stack-based buffer overflow triggered by a crafted RTF/DOC Office document parsed by wwlib.dll ↗
- →The invalid size used in a pointer calculation can be observed in the ECX register at the time of the access violation (ecx=003ad1a3); monitor for anomalous large size values in wwlib.dll memory operations ↗
- →Exploitation may also manifest as an arbitrary free from controlled pointers in the destination buffer after a successful oversized memcpy; monitor for heap corruption indicators in winword.exe/wwlib.dll ↗
- →The exploit was generated using a chunk reordering strategy against RTF/DOC files; inspect incoming Office documents (especially RTF) for malformed or reordered chunk structures ↗
- →Crash call stack involves wwlib!FMain and wwlib!DllCanUnloadNow offsets; presence of these in crash telemetry for Word 2007 (wwlib.dll 12.0.6707.5000) is indicative of CVE-2015-0064 exploitation ↗
- ·Crash reproduces on Windows Server 2003 and Windows 7; detection/hunting should prioritize these OS environments for legacy deployments ↗
