Who should care
Security teams responsible for systems that still run Adobe Flash Player, especially legacy browser-integrated Flash deployments, should pay attention. Endpoint and application owners should also care if any supported or archived environment still exposes Flash Player versions at or below 24.0.0.194.
Technical summary
The source data describes an exploitable memory corruption issue occurring during garbage collection. NVD maps the weakness to CWE-787 and rates the issue CVSS 3.1 8.8 HIGH with network attack vector, low attack complexity, no privileges required, and required user interaction. The vulnerable CPE entries identify Adobe Flash Player variants for Chrome, Edge, Internet Explorer, and the desktop runtime, with affected versions ending at 24.0.0.194.
Defensive priority
High. The vulnerability has high impact potential and low complexity, but exploitation requires user interaction. Treat it as urgent anywhere Flash remains present or cannot be fully removed.
Recommended defensive actions
- Apply the Adobe security update referenced in the vendor advisory for APSB17-04.
- Inventory all systems and browser profiles that may still include Adobe Flash Player or Flash Player desktop runtime components.
- Remove or disable Flash Player wherever possible, especially in legacy browser-integrated environments.
- Verify version levels against the NVD affected-version boundary of 24.0.0.194 and earlier.
- Prioritize remediation on endpoints and applications that handle untrusted web content or user-supplied Flash content.
- Review detections and protections for memory-corruption exploitation attempts in affected environments.
