Microsoft PowerPoint 2002 SP3, 2003 SP3, 2007 SP2, and 2010; Office 2004, 2008, and 2011 for Mac; Open XML File Format Converter for Mac; Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats SP2; PowerPoint Viewer; PowerPoint Viewer 2007 SP2; and PowerPoint Web App do not properly validate PersistDirectoryEntry records in PowerPoint documents, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a Slide with a malformed record, which triggers an exception and later use of an unspecified method, aka "Persist Directory RCE Vulnerability."
Untrusted search path vulnerability in Microsoft PowerPoint 2010 allows local users, and possibly remote attackers, to execute arbitrary code and conduct DLL hijacking attacks via a Trojan horse pptimpconv.dll that is located in the same folder as a .odp, .pot, .potm, .potx, .ppa, .pps, .ppsm, .ppsx, .ppt, .pptm, .pptx, .pwz, .sldm, or .sldx file.
Unspecified vulnerability in Microsoft Powerpoint allows remote user-assisted attackers to execute arbitrary code via unknown attack vectors, as exploited by Trojan.PPDropper.G. NOTE: as of 20070213, it is not clear whether this is the same issue as CVE-2006-5296, CVE-2006-4694, CVE-2006-3876, CVE-2006-3877, or older issues.
