Heap-based buffer overflow in Microsoft Office Word enables local code execution with full user-level impact when a victim opens a specially crafted document. Affected products span Microsoft 365 Apps for Enterprise, Office LTSC 2021 and 2024 (both Windows and Mac), and Office 365 for Mac. No public exploit identified at time of analysis, and no CISA KEV listing; however, the CVSS 7.8 score and complete C/I/A impact triad reflect the severity of arbitrary code execution achievable through a standard phishing or malicious file delivery scenario.
Local code execution in Microsoft Office is possible through a heap-based buffer overflow (CWE-822) that triggers when a user opens a maliciously crafted document. The CVSS 7.8 vector (AV:L/AC:L/PR:N/UI:R) reflects a classic client-side file-format attack requiring user interaction but no prior authentication, yielding full confidentiality, integrity, and availability impact on the targeted workstation. There is no public exploit identified at time of analysis and the CVE is not listed in CISA KEV, but Office document parsers are historically high-value targets and the vulnerability was reported by Microsoft's own MSRC team.
Local code execution in Microsoft Office Word arises from an untrusted pointer dereference (CWE-822) that can be triggered when a victim opens a crafted document. Successful exploitation grants the attacker the privileges of the current user with high impact to confidentiality, integrity, and availability, though no public exploit identified at time of analysis. The CVSS 3.1 base score of 7.8 reflects the requirement for user interaction but no prior authentication.
Local code execution in Microsoft Office Word is possible when a user opens a maliciously crafted document that triggers an untrusted pointer dereference (CWE-416 use-after-free).
