CVE-2015-8638: Use-after-free vulnerability in Adobe Flash Player before 18.0.0.324 and 19.x and 20.x before 20.0.0.267 on...

Security readout for executives and security teams

CVE-2015-8638 is a memory safety flaw in Adobe Flash Player and Adobe AIR. A successful attack could let an attacker run code on a user’s system. The affected software is legacy, but any remaining installations of the listed versions should be treated as high-risk exposure. Exposure is likely limited to environments that still retain the affected Flash Player or Adobe AIR versions, including packaged enterprise images, legacy browsers, old Linux repositories, or applications bundled with AIR components. Prioritize remediation where Flash or AIR remains installed on user workstations or legacy application servers. The business risk is arbitrary code execution in obsolete client-side software, but urgency depends on whether vulnerable components are still present. Mitigation focus: Upgrade Flash Player and Adobe AIR components to the fixed versions or later named by Adobe.; Check Linux distribution advisories for vendor-packaged Flash updates or removal guidance.; Inventory Adobe AIR SDK and Compiler installations, not only browser plugins..
