Summary

Integer overflow in Microsoft Office PowerPoint 2002 SP3 and 2003 SP3 allows remote attackers to execute arbitrary code via a PowerPoint file containing a crafted record type for "collaboration information for different slides" that contains a field that specifies a large number of records, which triggers an under-allocated buffer and a heap-based buffer overflow, aka "Integer Overflow Vulnerability."

37.86% chance of exploitation in the next 30 days, higher than 98% of all scored CVEs (FIRST EPSS, 2026-11-08).

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
