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
Heap-based buffer overflow in RealNetworks RealPlayer before 16.0.1.18 and RealPlayer SP 1.0 through 1.1.5 allows remote attackers to execute arbitrary code via a malformed MP4 file.

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

A heap-based buffer overflow vulnerability exists in RealNetworks RealPlayer's MP4 file parsing functionality. When processing a malformed MP4 file, the application writes data beyond allocated heap buffer boundaries without proper length validation, allowing an attacker to overwrite adjacent memory and achieve arbitrary code execution with the privileges of the running user.

MitigationUpgrade RealPlayer to version 16.0.1.18 or later. Until patched, avoid opening MP4 files from untrusted sources and consider disabling RealPlayer file associations or using application whitelisting to block unapproved media file execution.

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. Verify RealPlayer installation
    Check for RealPlayer on Windows via registry at HKLM\SOFTWARE\RealNetworks\RealPlayer or look for executable at common paths like C:\Program Files\Real\RealPlayer\realplay.exe
    Affected if RealPlayer is found installed on the system
  2. Identify installed RealPlayer version
    Right-click realplay.exe, select Properties, then view Version tab; or run realplay.exe and check Help > About RealPlayer
    Affected if Version cannot be determined or is within affected ranges
  3. Compare against vulnerable versions
    Match your installed version number against: RealPlayer <= 16.0.0.282; versions 4,5,6,7,8,10.0,10.5,11.0,11.0.1,11.0.2,11.0.2.1744; or RealPlayer SP versions 1.0.0,1.0.1,1.0.2,1.0.5,1.1,1.1.1,1.1.2,1.1.3,1.1.4,1.1.5
    Affected if Installed version matches any of the listed vulnerable versions
  4. Assess MP4 exposure
    Check if RealPlayer is configured to handle MP4 files by examining file associations or default application settings for .mp4 extension
    Affected if RealPlayer is associated with or regularly opens MP4 files

A user is affected if RealPlayer or RealPlayer SP is installed with a version matching the vulnerable ranges listed and the application handles MP4 files.

dbcve · scoped
Upgrade available Upgrade to a release after 16.0.0.282
Interim mitigation

Upgrade RealPlayer to version 16.0.1.18 or later. Until patched, avoid opening MP4 files from untrusted sources and consider disabling RealPlayer file associations or using application whitelisting to block unapproved media file execution.

Recommended fix High confidence

RealPlayer 16.0.1.18 or later; RealPlayer SP version after 1.1.5 (if still supported)

  1. 1. Uninstall the current version of RealPlayer or RealPlayer SP if installed
  2. 2. Navigate to the official RealNetworks download page at service.real.com
  3. 3. Download the latest version of RealPlayer (16.0.1.18 or later)
  4. 4. Install the downloaded version following the on-screen prompts
  5. 5. Verify the installed version by checking 'Help' > 'About RealPlayer' to confirm the version number
Caveat Legacy features may be removed in newer versions; older codecs or playback functionality could be affected
