Microsoft has released 1 security bulletins to fix newly discovered flaws in their software. Qualys has released the following checks for these new vulnerabilities:
Previously Microsoft has identified this as a zero day vulnerability in Microsoft PowerPoint.
The application is prone to the following vulnerabilities that are caused due to the way it handles specially crafted PowerPoint files.
- A file format vulnerability exists in the way that PowerPoint reads paragraph formatting data from specially crafted PowerPoint 4.0 files. (CVE-2009-0220)
- Multiple integer overflow and memory corruption vulnerabilities exist in the way PowerPoint reads an invalid record type in a specially crafted PowerPoint file allowing memory corruption and code execution. (CVE-2009-0221, CVE-2009-0224)
- Multiple file format vulnerabilities exist in the way PowerPoint reads sound data from specially crafted PowerPoint 4.0 files. (CVE-2009-0222, CVE-2009-0223, CVE-2009-0226, CVE-2009-0227, CVE-2009-1137)
- Multiple PP7 memory corruption vulnerabilities exists in the way PowerPoint reads sound data from specially crafted PowerPoint 95 files and older PowerPoint 95 formatted files. (CVE-2009-0225, CVE-2009-1128, CVE-2009-1129)
- A memory corruption vulnerability exists in the way PowerPoint accesses an invalid object in memory when parsing a specially crafted PowerPoint file. (CVE-2009-0556)
- A heap corruption vulnerability exists in the way PowerPoint reads a malformed structure value in a specially crafted PowerPoint file. (CVE-2009-1130)
- A data out of bounds vulnerability exists in the way Microsoft Office PowerPoint reads data that is too large in a specially crafted PowerPoint file. (CVE-2009-1131)
Microsoft has released a security update that addresses these vulnerabilities by modifying the way that PowerPoint handles conditions that could cause memory corruption when opening specially crafted PowerPoint files.

Workaround for all CVE-IDs:
Avoid opening Office files received from un-trusted sources.
Workarounds for CVE-2009-0221, CVE-2009-0224, CVE-2009-0556, CVE-2009-1130:
1) Use the Microsoft Office Isolated Conversion Environment (MOICE) when opening files from unknown or un-trusted sources because it protects Office 2003 installations by more securely opening Word, Excel, and PowerPoint binary format files.
Impact of workaround: Office 2003 and earlier formatted documents that are converted to the 2007 Microsoft Office System Open XML format by MOICE lose their macro functionality. Documents protected with passwords and Digital Rights Management cannot be converted.
2) Microsoft Office File Block policy should be used to block the opening of Office 2003 and earlier documents from unknown or untrusted sources.
Impact of workaround: If File Block policy is configured without special "exempt directory" configuration (see KB922848), Office 2003 files or earlier versions will not open in Office 2003 or 2007 Microsoft Office System.
Workaround for CVE-2009-0220, CVE-2009-0222, CVE-2009-0223, CVE-2009-0226, CVE-2009-0227, CVE-2009-1137:
Restrict access to pp4x322.dll in Microsoft Office PowerPoint 2000 or Microsoft Office PowerPoint 2002
Impact of workaround: It will prevent PowerPoint 4.0 files from being opened
Workaround for CVE-2009-0225, CVE-2009-1128, CVE-2009-1129:
Restrict access to pp7x32.dll in Microsoft Office PowerPoint 2000 or Microsoft Office PowerPoint 2002
Impact of workaround: It will prevent PowerPoint 95 files from being opened
Details on the workarounds can be found at MS09-017.
