Vulnerabilities > CVE-2017-0254 - Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in Microsoft products
Summary
Microsoft Word 2007, Office 2010 SP2, Word 2010 SP2, Office Compatibility Pack SP3, Office for Mac 2011, Office for Mac 2016, Microsoft Office Web Apps 2010 SP2, Office Web Apps Server 2013 SP1, Word 2013 RT SP1, Word 2013 SP1, Word Automation Services on Microsoft SharePoint Server 2013 SP1, Office Word Viewer, SharePoint Enterprise Server 2016, and Word 2016 allow a remote code execution vulnerability when the software fails to properly handle objects in memory, aka "Microsoft Office Memory Corruption Vulnerability". This CVE ID is unique from CVE-2017-0264 and CVE-2017-0265.
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Overflow Buffers Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
- Client-side Injection-induced Buffer Overflow This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
- Filter Failure through Buffer Overflow In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
- MIME Conversion An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

NASL family MacOS X Local Security Checks NASL id MACOSX_MS17_MAY_OFFICE.NASL description The Microsoft Office application installed on the remote macOS or Mac OS X host is missing a security update. It is, therefore, affected by a remote code execution vulnerability due to a failure to properly handle objects in memory. An unauthenticated, remote attacker can exploit this, by convincing a user to open a specially crafted Office document or visit a specially crafted website, to execute arbitrary code in the context of the current user. last seen 2020-06-01 modified 2020-06-02 plugin id 100295 published 2017-05-19 reporter This script is Copyright (C) 2017-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/100295 title Security Update for Microsoft Office (May 2017) (macOS)
