ATMFD.DLL Memory Corruption Vulnerability in Microsoft Windows

IdentifiersCVE-2015-2387CWE-119

CVE-2015-2387 is a local elevation of privilege vulnerability in ATMFD.DLL, the Adobe Type Manager Font Driver in Microsoft Windows. According to the provided content, affected 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 flaw is described as a memory corruption issue in ATMFD.DLL that can be triggered by a crafted application. Successful exploitation allows a local user to elevate privileges on the target system. The content also indicates this vulnerability was used in the wild, including by APT28/Sednit and in tooling derived from the Hacking Team leak, as part of post-compromise privilege escalation chains.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation results in local privilege escalation on the affected Windows host. An attacker who already has code execution as a local user can leverage the vulnerability to obtain higher privileges, potentially up to administrative or SYSTEM-level execution depending on exploit conditions. This can enable full compromise of the local machine, including disabling defenses, credential theft, persistence installation, access to protected data, and use of the host for further lateral movement.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, reduce opportunities for local code execution by restricting execution of untrusted applications, enforcing application allowlisting, limiting user rights, and monitoring for suspicious child processes or exploit behavior associated with privilege escalation. Additional mitigations include hardening endpoints against phishing-delivered malware, using EDR to detect abnormal privilege transitions and kernel/driver exploitation behavior, and isolating or decommissioning legacy Windows systems that remain vulnerable. The provided content does not include a vendor-specific workaround beyond patching.

Remediation

Patch, then assume compromise.

Apply the relevant Microsoft security update for CVE-2015-2387 on all affected Windows systems. Prioritize legacy and unsupported systems listed in the content, especially where local code execution by untrusted users is possible. Standard remediation should include verifying that ATMFD.DLL-related patches are installed across the fleet, accelerating retirement of unsupported Windows versions, and validating patch deployment on endpoints commonly exposed to phishing-delivered malware that may use this vulnerability for post-exploitation privilege escalation.
