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 the RV40 codec 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 a crafted RV40 RealVideo video 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

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. Confirm RealPlayer is installed
    Search for RealPlayer executable on the system (typical installation paths include Program Files/RealPlayer or Program Files/Real/RealPlayer). Look for files named RealPlayer.exe or realplay.exe
    Affected if RealPlayer executable is found on the system
  2. Determine installed RealPlayer version
    Right-click the RealPlayer executable, select Properties, then view the Details tab for version information. Alternatively, check the About section within RealPlayer's Help menu
    Affected if Installed version is 11.0, 11.0.1, 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, or any RealPlayer SP version between 1.0 and 1.1.5, or version 15.x prior to 15.02.71
  3. Verify RV40 codec is present
    The vulnerability exists in the RV40 codec component. Check RealPlayer's codec information or supported formats list (accessible through Player preferences or codec viewer)
    Affected if RV40 codec support is listed as available in RealPlayer
  4. Confirm RealVideo file handling is enabled
    Check if RealPlayer is configured to handle .rv or .rmvb file extensions (check file association settings or try opening a RealVideo file with RealPlayer)
    Affected if RealPlayer can open or is associated with RealVideo files

User is affected if RealPlayer version 11.x, 14.x before 15.02.71, or RealPlayer SP 1.0-1.1.5 is installed with RV40 codec support and ability to process RealVideo files.

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

Upgrade RealPlayer to version 15.02.71 or later. Avoid opening untrusted or unexpected RealVideo (.rv, .rmvb) files from untrusted sources.

Recommended fix High confidence

RealPlayer 15.0.2.71 or later

  1. 1. Uninstall the current version of RealPlayer or RealPlayer SP if installed
  2. 2. Download RealPlayer version 15.0.2.71 or later from the official RealNetworks service site (service.real.com)
  3. 3. Install the updated version of RealPlayer
  4. 4. Verify the installed version matches or exceeds 15.0.2.71
