Security readout for executives and security teams
CVE-2015-0091 is a remote code execution flaw in the Adobe Font Driver included with multiple legacy Microsoft Windows versions. A user visiting a crafted website or opening a crafted file could expose the machine to attacker-controlled code execution. The strongest concern is legacy system exposure, especially systems still processing untrusted documents or web content. Exposure is most likely on legacy Windows endpoints or servers that remain unpatched and allow users or services to handle untrusted websites, documents, or files. Modern, fully patched Windows systems are not identified as affected in the supplied bundle. Prioritize this for any remaining legacy Windows estate. The issue enables remote code execution, but urgency depends on whether affected systems still exist, are reachable by users or file-processing workflows, and are missing Microsoft’s 2015 security update. Mitigation focus: Apply Microsoft guidance and security updates from MS15-021 where applicable.; Retire, isolate, or tightly restrict unsupported affected Windows systems.; Limit exposure to untrusted websites, documents, and file ingestion until remediated..
