Security readout for executives and security teams
Plain-English summary
CVE-2015-2431 is a remote code execution issue in legacy Microsoft Office, Live Meeting, and Lync components. A crafted Office Graphics Library font could let an attacker run code when processed by affected software. Business urgency depends on whether these old products remain installed.
Executive priority
Treat this as a legacy-software risk with high impact if affected systems remain. Prioritize confirming whether these products still exist, then patch, isolate, or retire them.
Technical view
The vulnerability affects the Microsoft Office Graphics Component handling of OGL fonts in Office 2007 SP3, Office 2010 SP2, Live Meeting 2007 Console, Lync 2010, Lync 2010 Attendee, Lync 2013 SP1, and Lync Basic 2013 SP1.
Likely exposure
Exposure is most likely on legacy Windows endpoints, virtual desktops, or archived application images that still include affected Office, Live Meeting, or Lync versions.
Exploitation context
The source bundle includes an Exploit-DB reference, indicating public exploit information exists. The bundle does not show CISA KEV listing or other evidence of active exploitation.
Researcher notes
No CVSS, CWE, or detailed affected CPE data is present in the bundle. Analysis relies on the CVE description, Microsoft advisory reference, and public exploit-reference tag without adding exploit mechanics.
Mitigation direction
- Apply Microsoft guidance and updates from MS15-080.
- Retire or remove affected legacy Office, Live Meeting, and Lync software where possible.
- Limit opening Office documents from untrusted sources on exposed legacy systems.
- Check vendor guidance for supported replacement or hardening options.
Validation and detection
- Inventory endpoints for the affected Microsoft product versions listed in MS15-080.
- Confirm whether MS15-080 security updates are installed on remaining affected systems.
- Review mail and web controls for handling untrusted Office attachments.
- Check security telemetry for suspicious Office or Lync process behavior.
