Heap-based buffer overflow in Microsoft Office PowerPoint allows an unauthorized attacker to execute code locally.
AnalysisAI
Local code execution in Microsoft Office PowerPoint (including Microsoft 365 Apps, Office 2019, Office LTSC 2021/2024, and their macOS variants) arises from a heap-based buffer overflow triggered when a victim opens a maliciously crafted presentation file. Successful exploitation runs attacker-controlled code with the privileges of the current user, yielding full confidentiality, integrity, and availability impact. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV, but Microsoft has released a patch.
