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 analysis · high confidence

Use-after-free vulnerability in Adobe Flash Player and Adobe AIR allows remote attackers to execute arbitrary code. The vulnerability exists in unspecified vectors within the software before patched versions (18.0.0.268, 20.0.0.228, 11.2.202.554 for Linux, and 20.0.0.204 for AIR).

MitigationUpdate Adobe Flash Player to version 18.0.0.268/20.0.0.228 (or 11.2.202.554 on Linux) and Adobe AIR/SDK to version 20.0.0.204, or migrate away from Flash as it reaches end-of-life.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed Adobe Flash Player version
    Check the Flash Player version through the About dialog in the browser or by examining the Flash plugin file version. On Windows, this is typically in the System32 directory for system-level installations or within browser plugin directories.
    Affected if The installed version is 18.0.0.261 or earlier, OR one of these specific versions: 19.0.0.185, 19.0.0.207, 19.0.0.226, or 19.0.0.245. On Linux, versions 11.2.202.548 or earlier are affected.
  2. Identify installed Adobe AIR version
    Check the Adobe AIR version through the AIR Application Installer or by examining the AIR runtime installation directory.
    Affected if The installed version is 19.0.0.241 or earlier.
  3. Identify installed Adobe AIR SDK version
    Check the Adobe AIR SDK version by examining the SDK installation directory or checking the SDK version property.
    Affected if The installed AIR SDK or AIR SDK & Compiler version is 19.0.0.241 or earlier.
  4. Determine if Flash or AIR is actively used
    Review installed browsers and applications for Adobe Flash Player plugins or Adobe AIR-based applications.
    Affected if Any of the above affected versions are installed and the software is in use.

Your environment is affected if any installation of Adobe Flash Player (versions listed above), Adobe AIR, or Adobe AIR SDK matches the vulnerable version ranges specified.

Interim mitigation

Update Adobe Flash Player to version 18.0.0.268/20.0.0.228 (or 11.2.202.554 on Linux) and Adobe AIR/SDK to version 20.0.0.204, or migrate away from Flash as it reaches end-of-life.

Recommended fix High confidence

Flash Player: 18.0.0.268 (Windows/OS X), 11.2.202.554 (Linux); AIR/AIR SDK/AIR SDK & Compiler: 20.0.0.204

  1. Identify which Adobe product is installed: Flash Player, Adobe AIR, Adobe AIR SDK, or Adobe AIR SDK & Compiler
  2. For Flash Player on Windows/OS X: Upgrade to version 18.0.0.268 or later (19.x/20.x users should upgrade to 20.0.0.228 or later)
  3. For Flash Player on Linux: Upgrade to version 11.2.202.554 or later
  4. For Adobe AIR: Upgrade to version 20.0.0.204 or later
  5. For Adobe AIR SDK: Upgrade to version 20.0.0.204 or later
  6. For Adobe AIR SDK & Compiler: Upgrade to version 20.0.0.204 or later
  7. Download the appropriate fixed version from the official Adobe security bulletin (APSB15-32)
  8. Uninstall the current vulnerable version
Caveat Adobe Flash Player reached end-of-life on December 31, 2020; consider migrating away from Flash-based content
