Detection & IOCsextracted from sources · hover to see the quote
- →Attack vector involves crafted Office documents (e.g., RTF) with specially crafted embedded fonts delivered via email attachment or web-based lure; monitor for Office processes spawning unexpected child processes after opening such documents. ↗
- →The Preview Pane is an attack vector for products rated Critical; monitor for exploitation attempts triggered without explicit file open actions in Office applications. ↗
- →Workaround registry key for Office 2010: block RTF files via HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Word\Security\FileBlock with RtfFiles DWORD=2; absence of this key on unpatched systems indicates exposure. ↗
- →Workaround registry key for Office 2007: block RTF files via HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\12.0\Word\Security\FileOpenBlock with RtfFiles DWORD=1; absence indicates exposure. ↗
- →Workaround registry key for Office 2013: block RTF files via HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Word\Security\FileBlock with RtfFiles DWORD=2; absence indicates exposure. ↗
- ·Exploit status is not publicly disclosed or actively exploited at time of advisory publication; exploitation assessed as 'Less Likely' for older software releases. ↗
- ·Update 3115121 only applies to specific configurations of Microsoft Office 2010; not all Office 2010 installs will be offered the patch, requiring manual verification of applicability. ↗
- ·The vulnerability resides in the Windows font library's handling of embedded fonts within Office documents; the fix corrects how the library processes these fonts. ↗
