CVE-2017-11281
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAdobe Flash Player has an exploitable memory corruption vulnerability in the text handling function. Successful exploitation could lead to arbitrary code execution. This affects 26.0.0.151 and earlier.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysisThe program reads or writes outside the bounds of an allocated buffer, corrupting adjacent memory. With crafted input an attacker can overwrite control data and, with effort, redirect execution to their own code. Remediation ranges from bounds checking and safe library functions to compiler mitigations, usually alongside a careful audit of the surrounding code.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedRemove/uninstall Flash Player (EOL product) - if upgrade required, Adobe Flash Player 26.0.0.153 or later via official Adobe channels
- 1. Check if Adobe Flash Player is installed on the system
- 2. Since Adobe Flash Player reached end-of-life on December 31, 2020, the recommended action is to uninstall/remove Flash Player entirely rather than upgrade
- 3. On Windows: Use Control Panel > Programs and Features to uninstall Adobe Flash Player
- 4. On Linux: Remove flash-plugin package via package manager (e.g., yum remove flash-plugin or apt remove flashplugin-installer)
- 5. Remove any remaining Flash Player directories and files (e.g., /usr/lib/flash-plugin/, ~/.macromedia/)
- 6. If Flash Player is required for legacy applications, apply Adobe's official patch from APSB17-28 which fixes this vulnerability in version 26.0.0.153 or later
- 7. Ensure the system has the latest Adobe Flash Player security updates if continued use is absolutely necessary
