Memory Safety in Microsoft Office 2007 … 2016
Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2018-0798 is a high-severity Out-of-bounds Write (CWE-787) vulnerability in Microsoft Office. Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Security Account Manager (T1003.002); ranked in the top 0.1% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
Equation Editor in Microsoft Office 2007, Microsoft Office 2010, Microsoft Office 2013, and Microsoft Office 2016 contains a memory corruption vulnerability that permits remote code execution. The flaw stems from improper handling of objects in memory and is tracked under CWE-787, with an associated CVSS 3.1 score of 8.8 reflecting network attack vector, low complexity, and no required privileges.
An unauthenticated remote attacker can exploit the issue by delivering a malicious document that triggers Equation Editor processing, resulting in arbitrary code execution with full confidentiality, integrity, and availability impact once user interaction occurs.
The Microsoft Security Response Center advisory at portal.msrc.microsoft.com and related trackers at securityfocus.com and securitytracker.com address the vulnerability, while a 0patch analysis discusses continued support options for the legacy Equation Editor component.
