Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

win32k.sys in the kernel-mode drivers is affected by a TrueType font parsing flaw that permits remote code execution. The impacted platforms include Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold and R2, and Windows RT Gold and 8.1. The issue is tracked as CWE-94 and carries a CVSS 3.1 score of 8.8.

An attacker can deliver a malicious TrueType font to a target system and trigger arbitrary code execution in kernel mode. The attack requires no authentication and can be initiated remotely, although user interaction is needed to process the font. Exploitation was observed in the wild during October 2014.

Microsoft addressed the vulnerability through the October 2014 security updates documented in bulletin MS14-058, which includes patches for the listed Windows versions. Additional details on risk and mitigation are provided in the associated Security Research & Defense blog post and vendor advisories.

The flaw received immediate attention because of confirmed in-the-wild exploitation at the time of disclosure.

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-94

Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.

addresses: CWE-94

Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.

addresses: CWE-94

Validates inputs used in dynamic code generation to block injected directives.

addresses: CWE-94

Directly prevents execution of attacker-supplied code written into data memory regions.

PR.PS-06 mostly match
prevents

PR.PS-06's SDLC practices directly target injection flaws via secure coding and testing (mostly), yet as a single broad outcome it leaves many code-generation specifics unaddressed (partial).

PR.DS-10 none match
prevents

PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.

prevents

Banning unapproved code samples and unauthenticated web services, combined with secure-coding standards and SAST, prevents the dynamic generation or inclusion of attacker-supplied code.

none

Controls that restrict unauthorized or malicious code from being introduced via external networks or removable media limit opportunities for an attacker to inject and execute arbitrary code.
