Security readout for executives and security teams
CVE-2015-2426 is a Windows font-handling flaw that can let an attacker run code if a user opens or previews content containing a crafted OpenType font. It affects multiple older Windows versions and is listed in CISA KEV, so organizations should treat unpatched legacy systems as urgent exposure. Exposure is most likely on unpatched Windows Vista, Server 2008, Windows 7, Windows 8/8.1, Server 2012, and Windows RT systems that process untrusted fonts or documents. Prioritize remediation for any legacy Windows estate. KEV status means this is not theoretical, and affected systems can face code execution through routine document or font processing. Mitigation focus: Apply Microsoft guidance and updates from MS15-078 where applicable.; Retire or isolate unsupported affected Windows systems.; Restrict handling of untrusted documents and fonts on legacy endpoints..
