CVE-2015-8651: Integer overflow in Adobe Flash Player before 18.0.0.324 and 19.x and 20.x before 20.0.0.267 on Windows and...

Integer overflow in Adobe Flash Player before 18.0.0.324 and 19.x and 20.x before 20.0.0.267 on Windows and OS X and before 11.2.202.559 on Linux, Adobe AIR before 20.0.0.233, Adobe AIR SDK before 20.0.0.233, and Adobe AIR SDK & Compiler before 20.0.0.233 allows attackers to execute arbitrary code via unspecified vectors.

Security readout for executives and security teams

This is an old but serious Adobe Flash/AIR code execution flaw. If vulnerable software processes malicious content, an attacker could run code with the user’s privileges. CISA KEV status means known exploitation is documented, so any remaining legacy Flash or AIR footprint deserves urgent removal or vendor-supported updating. Exposure is most likely in legacy endpoints, packaged applications, browsers, kiosks, or vendor images still carrying Flash Player, AIR, AIR SDK, or AIR SDK & Compiler versions below the fixed releases named in the CVE description. Treat as urgent legacy-risk cleanup. The vulnerability is high impact, known exploited, and tied to software that often persists outside normal patch workflows. The main business task is finding and eliminating residual Flash/AIR exposure, not studying exploit details. Mitigation focus: Inventory systems for Adobe Flash Player, Adobe AIR, AIR SDK, and AIR SDK & Compiler.; Update to the fixed versions named by Adobe and operating-system vendors where still applicable.; Remove legacy Flash or AIR components where business use is no longer justified..

Integer Overflow or Wraparound

Integer Overflow or Wraparound represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
