Microsoft PowerPoint 2002 SP3, 2003 SP3, and 2007 SP2; Office 2004 and 2008 for Mac; Open XML File Format Converter for Mac; Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats SP2; and PowerPoint Viewer 2007 SP2 do not properly handle Office Art containers that have invalid records, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a PowerPoint document with a container that triggers certain access to an uninitialized object, aka "OfficeArt Atom RCE Vulnerability."

Microsoft Crypto API 5.131.2600.2180 through 6.0, as used in Outlook, Windows Live Mail, and Office 2007, performs Certificate Revocation List (CRL) checks by using an arbitrary URL from a certificate embedded in a (1) S/MIME e-mail message or (2) signed document, which allows remote attackers to obtain reading times and IP addresses of recipients, and port-scan results, via a crafted certificate with an Authority Information Access (AIA) extension.
