Multiple stack-based buffer overflows in the PowerPoint 95 importer (PP7X32.DLL) in Microsoft Office PowerPoint 2000 SP3, 2002 SP3, and 2003
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.

Remediation
Which version to upgrade to
Fix versions compiled from the vendor, package registries and Microsoft. Verify the vendor's note before upgrading.
No fix version is recorded for this entry. Check the references for vendor advisories.
Exploit status
No known public exploit
No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.
Research context
For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.
Timeline
From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.
No dated events beyond publication.
FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).
Patch and commit links
Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

Variant candidates
Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.
No nightly-computed relations.
Chain candidates
An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
