CVE-2012-5676
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 · uneditedBuffer overflow in Adobe Flash Player before 10.3.183.48 and 11.x before 11.5.502.135 on Windows, before 10.3.183.48 and 11.x before 11.5.502.136 on Mac OS X, before 10.3.183.48 and 11.x before 11.2.202.258 on Linux, before 11.1.111.29 on Android 2.x and 3.x, and before 11.1.115.34 on Android 4.x; Adobe AIR before 3.5.0.880 on Windows and before 3.5.0.890 on Mac OS X; and Adobe AIR SDK before 3.5.0.880 on Windows and before 3.5.0.890 on Mac OS X allows attackers to execute arbitrary code via unspecified vectors.
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.

- Identify the currently installed Adobe AIR version by checking the version in the application's properties or the AIR version checker
- For Flash Player: Download and install the appropriate fixed version based on your platform and version branch: 10.3.183.48 or later for 10.3.x, 11.5.502.135 (Windows)/11.5.502.136 (Mac) or later for 11.5.x, 11.2.202.258 or later for Linux 11.2.x, 11.1.111.29 or later for Android 2.x/3.x, 11.1.115.34 for Android 4.x
- For Adobe AIR: Download and install version 3.5.0.880 (Windows) or 3.5.0.890 (Mac) or later
- For Adobe AIR SDK: Update to version 3.5.0.880 (Windows) or 3.5.0.890 (Mac) or later via Adobe's official channels
- Verify the update was successful by checking the version numbers again
- Consider migrating away from Flash Player as it reached end-of-life on December 31, 2020; HTML5 alternatives are recommended for long-term security
