Office Online Server

Microsoft Excel and Office products are vulnerable to local code execution through unsafe pointer dereferencing, requiring user interaction to trigger. An attacker with local access can exploit this flaw to achieve arbitrary code execution with full system privileges. No patch is currently available, leaving users of affected Office versions at risk.

Arbitrary code execution in Microsoft Office Excel and related products (Office Online Server, 365 Apps) via out-of-bounds memory read allows local attackers to achieve complete system compromise without requiring user interaction or elevated privileges. This high-severity vulnerability affects multiple Microsoft Office components and currently lacks a security patch. An attacker with local access can exploit memory corruption to execute malicious code with full system permissions.

Heap buffer overflow in Microsoft Office Excel enables local code execution with high integrity and confidentiality impact affecting Office, Office Online Server, and 365 Apps. An attacker with user interaction can achieve arbitrary code execution in the context of the affected application. No patch is currently available for this vulnerability.

Use after free in Microsoft Office Excel allows an unauthorized attacker to execute code locally. [CVSS 7.8 HIGH]

Information disclosure in Microsoft Office Excel and related products results from an out-of-bounds read vulnerability that requires local access and user interaction to exploit. An attacker can leverage this flaw to read sensitive data from memory on an affected system. No patch is currently available for this vulnerability affecting Office Long Term Servicing Channel, 365 Apps, and Office Online Server.

Privilege escalation in Microsoft Office Excel (including 365 Apps and Long Term Servicing Channel) via heap-based buffer overflow allows local attackers with user interaction to gain elevated system privileges. The vulnerability affects multiple Office product lines and currently lacks a security patch. With a CVSS score of 7.8, this poses a significant risk to organizations using affected Excel versions.

Information disclosure in Microsoft Excel allows local attackers with user interaction to read sensitive data through improper input validation in Office 365 Apps and Long Term Servicing Channel. An attacker must socially engineer a user into opening a specially crafted file to trigger the vulnerability. No patch is currently available for this medium-severity issue.

Arbitrary code execution in Microsoft Office Excel results from an integer underflow vulnerability in the Long Term Servicing Channel and Online Server editions, exploitable by local attackers with user interaction. This HIGH severity flaw (CVSS 7.8) grants full system compromise capabilities including code execution, data theft, and service disruption with no available patch.

Arbitrary code execution in Microsoft Excel through unsafe pointer handling enables local attackers to achieve full system compromise without requiring elevated privileges. This vulnerability affects Microsoft 365 Apps, Office, Office Online Server, and Office Long Term Servicing Channel across multiple versions. No patch is currently available, leaving affected systems vulnerable to exploitation via maliciously crafted spreadsheets.
