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
Unspecified vulnerability in RealNetworks RealPlayer 11.x, 14.x, and 15.x before 15.02.71, and RealPlayer SP 1.0 through 1.1.5, allows remote attackers to execute arbitrary code via vectors involving the coded_frame_size value in a RealAudio audio stream.

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

Buffer overflow vulnerability in RealPlayer's handling of RealAudio streams where the coded_frame_size value in the audio stream is not properly validated before being used in memory operations, allowing an attacker to overwrite memory and execute arbitrary code via a specially crafted media file.

MitigationUpgrade RealPlayer to version 15.02.71 or later. Alternatively, remove or disable RealPlayer and use alternative media players until patching can be completed.

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 RealPlayer product
    Check Programs and Features (Windows) or Application folder (Mac) for Realnetworks RealPlayer or RealPlayer SP
    Affected if Neither RealPlayer nor RealPlayer SP is installed, then not affected
  2. Obtain RealPlayer version number
    Open RealPlayer, go to Help > About RealPlayer to display the version string
    Affected if Version matches any of: 14.0.0, 14.0.1, 14.0.1.609, 14.0.1.633, 14.0.2, 14.0.3, 14.0.4, 14.0.5, 14.0.6, 14.0.7, 11.0, or 11.0.1
  3. Obtain RealPlayer SP version number
    Open RealPlayer SP, check Help > About for version information
    Affected if Version matches any of: 1.0.0, 1.0.1, 1.0.2, 1.0.5, 1.1, 1.1.1, 1.1.2, 1.1.3, 1.1.4, or 1.1.5
  4. Confirm RealAudio stream handling is enabled
    RealPlayer processes RealAudio streams by default when opening media files; verify RealPlayer is configured to handle .ra, .ram, .rmm audio file types
    Affected if RealPlayer or RealPlayer SP version is in the affected list AND the application is configured to handle RealAudio media files

You are affected if RealPlayer version 14.0.0-14.0.7, 11.0-11.0.1, or RealPlayer SP version 1.0.0-1.1.5 is installed and configured to process RealAudio streams.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade RealPlayer to version 15.02.71 or later. Alternatively, remove or disable RealPlayer and use alternative media players until patching can be completed.

Recommended fix High confidence

RealPlayer 15.0.2.71 or later (RealPlayer SP was consolidated into main RealPlayer product)

  1. 1. Uninstall the affected RealPlayer version (14.0.0, 14.0.1, 14.0.1.609, 14.0.1.633 or RealPlayer SP 1.0.x-1.1.5)
  2. 2. Navigate to the official RealNetworks download page at service.real.com
  3. 3. Download the latest version of RealPlayer (version 15.0.2.71 or later)
  4. 4. Install the new version following the installation wizard prompts
  5. 5. Verify the installed version by checking Help > About RealPlayer
Caveat RealPlayer SP was discontinued; users should migrate to the main RealPlayer application. Ensure any saved playlists or preferences are backed up before uninstallation.
