CVE-2009-1129: Microsoft Office PowerPoint

High severity, CVSS 9.3. EPSS: 35.7% chance of exploitation in the next 30 days.

Multiple stack-based buffer overflows in the PowerPoint 95 importer (PP7X32.DLL) in Microsoft Office PowerPoint 2000 SP3, 2002 SP3, and 2003 SP3 allow remote attackers to execute arbitrary code via an inconsistent record length in sound data in a file that uses a PowerPoint 95 (PPT95) native file format, aka "PP7 Memory Corruption Vulnerability," a different vulnerability than CVE-2009-1128.
