Microsoft Word 2007 SP2, Office 2010 SP2, Word 2013 SP1, Word 2013 RT SP1, Word 2016, Word for Mac 2011, Word 2016 for Mac, Office Compatibility Pack SP3, Word Viewer, Word Automation Services on SharePoint Server 2010 SP2 and 2013 SP1, Office Web Apps 2010 SP2, Office Web Apps Server 2013 SP1, and Office Online Server contain a memory corruption vulnerability tracked as CVE-2016-7193 and CWE-119. The flaw is triggered when these components process a specially crafted RTF document, resulting in arbitrary code execution.

An unauthenticated remote attacker can exploit the issue by supplying a malicious RTF file that a user opens in an affected Microsoft Word or Office application. Successful exploitation grants the attacker the ability to execute arbitrary code with the privileges of the current user, affecting confidentiality, integrity, and availability.

The Microsoft security bulletin MS16-121, referenced in the advisory at https://docs.microsoft.com/en-us/security-updates/securitybulletins/2016/ms16-121, addresses the vulnerability through security updates for the listed products and recommends applying the patches as the primary mitigation.

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-119

Ongoing control assessments and code testing (static/dynamic analysis, fuzzing) surface memory buffer restriction failures, which are then remediated before release.

addresses: CWE-119

Managed runtimes used by platform-independent applications (e.g., JVM, CLR) enforce memory safety, preventing most buffer overflows that require direct memory manipulation.

addresses: CWE-119

Memory protections (e.g., W^X, ASLR) make exploitation of buffer-boundary violations far harder to turn into code execution.

addresses: CWE-119

Detects exploitation attempts that produce memory corruption, crashes, or anomalous behavior.

finds

Security testing in development catches out-of-bounds accesses before release, covering most instances of the weakness.

prevents

Secure development lifecycle mandates memory-safety practices that directly prevent buffer-boundary violations.

prevents

Application security requirements can specify memory-safety rules, but do not prescribe implementation details.

prevents

Secure architecture and engineering principles include memory-safe design patterns that mitigate buffer overflows.

prevents

Secure coding standards explicitly forbid unsafe buffer operations, directly eliminating CWE-119.
