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 · unedited
Adobe Flash Player before 10.3.183.20 and 11.x before 11.3.300.257 on Windows and Mac OS X; before 10.3.183.20 and 11.x before 11.2.202.236 on Linux; before 11.1.111.10 on Android 2.x and 3.x; and before 11.1.115.9 on Android 4.x, and Adobe AIR before 3.3.0.3610, allows attackers to execute arbitrary code or cause a denial of service (memory corruption) via unspecified vectors, a different vulnerability than CVE-2012-2037.

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

Memory corruption vulnerability in Adobe Flash Player and Adobe AIR allows remote attackers to execute arbitrary code or cause denial of service via unspecified vectors. Affected versions span multiple platforms (Windows, Mac, Linux, Android) and the CVSS 7.5 indicates high-severity network-exploitable code execution capability.

MitigationUpdate Adobe Flash Player to versions 10.3.183.20+/11.3.300.257+ (Windows/Mac), 11.2.202.236+ (Linux), 11.1.111.10+ (Android 2.x/3.x), 11.1.115.9+ (Android 4.x), and Adobe AIR to 3.3.0.3610+. Consider disabling Flash or restricting its use until patches are applied.

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. Check Adobe Flash Player version on Windows or Mac
    Navigate to Adobe Flash Player About page: Visit 'https://www.adobe.com/software/flash/about/' or on Windows check 'C:\Windows\System32\Macromed\Flash\FlashPlayerInstaller.exe' version, or on Mac check '/Library/Application Support/Adobe/Flash Player/' folder contents
    Affected if Installed version is 11.2.202.235 or lower, 11.1.115.8 or lower, or 11.1.111.9 or lower
  2. Check Adobe Flash Player version on Linux
    Run command: 'rpm -q flash-plugin' for RedHat/CentOS, or 'dpkg -l | grep flash' for Debian/Ubuntu, or check '/usr/lib/flash-plugin/libflashplayer.so' file version
    Affected if Installed version is 11.2.202.235 or lower on Linux
  3. Check Adobe AIR version
    On Windows check 'C:\Program Files\Adobe\Adobe AIR\Versions\1.0\Adobe AIR Application Installer.exe' properties, on Mac check '/Applications/Adobe AIR Installer.app' or run 'strings' on the binary to find version string
    Affected if Installed version is 3.2.0.2070 or lower
  4. Check browser plugin status
    In web browsers (Chrome, Firefox, IE), navigate to 'chrome://plugins' or 'about:addons' and verify if Flash Player plugin is enabled and note its version
    Affected if Flash plugin is enabled and version matches affected ranges listed above
  5. Check Red Hat Enterprise Linux flash-plugin package
    Run 'rpm -qa | grep -i flash' or 'yum list installed flash-plugin' on RHEL systems
    Affected if Package version corresponds to affected Adobe Flash Player versions (11.2.x before 11.2.202.236)
  6. Check for Adobe AIR installation directories
    Inspect 'C:\Program Files\Adobe\Adobe AIR' on Windows or '/Applications' folder on Mac for Adobe AIR presence and version files
    Affected if Adobe AIR is installed with version 3.2.0.2070 or lower

The environment is affected if Adobe Flash Player version is 11.2.202.235 or lower, 11.1.115.8 or lower, 11.1.111.9 or lower, or Adobe AIR version is 3.2.0.2070 or lower, regardless of operating system platform.

Upgrade available Upgrade to a release after 11.2.202.235
Interim mitigation

Update Adobe Flash Player to versions 10.3.183.20+/11.3.300.257+ (Windows/Mac), 11.2.202.236+ (Linux), 11.1.111.10+ (Android 2.x/3.x), 11.1.115.9+ (Android 4.x), and Adobe AIR to 3.3.0.3610+. Consider disabling Flash or restricting its use until patches are applied.

Recommended fix High confidence

Adobe Flash Player 11.2.202.236 or later (Linux); Adobe AIR 3.3.0.3610 or later

  1. 1. For Linux systems: Update Adobe Flash Player through the system package manager (e.g., 'yum update flash-plugin' or 'zypper update flash-player') to obtain version 11.2.202.236 or later
  2. 2. For Adobe AIR: Update Adobe AIR to version 3.3.0.3610 or later via the Adobe website or system package manager
  3. 3. For Android: Update Flash Player through Google Play Store to 11.1.115.9 (Android 4.x) or 11.1.111.10 (Android 2.x/3.x)
  4. 4. For Windows/Mac OS X: Download and install Flash Player 11.3.300.257 or later from Adobe's official website
  5. 5. Restart any affected browsers or applications after updating
  6. 6. Verify the installed version matches or exceeds the fixed versions (Flash Player 11.2.202.236 on Linux, AIR 3.3.0.3610)
Caveat Flash Player is deprecated and no longer supported since end-of-life; consider migrating away from Flash-based content
