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
The RealVideo renderer in RealNetworks RealPlayer before 15.0.0 and Mac RealPlayer before 12.0.0.1703 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via unspecified vectors.

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

The RealVideo renderer in RealPlayer contains a memory corruption vulnerability that allows remote attackers to execute arbitrary code or cause denial of service via unspecified vectors. This is a critical client-side vulnerability in the media rendering component affecting versions prior to 15.0.0 (Windows) and 12.0.0.1703 (Mac).

MitigationUpgrade to RealPlayer 15.0.0+ (Windows) or 12.0.0.1703+ (Mac). If immediate upgrade is not feasible, disable RealVideo playback functionality and restrict network exposure to untrusted content sources.

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 if RealPlayer is installed
    On Windows, open Control Panel > Programs and Features and look for RealPlayer or RealNetworks RealPlayer. On Mac, check /Applications folder for RealPlayer.app.
    Affected if RealPlayer is found on the system
  2. Identify the installed RealPlayer version
    Right-click the RealPlayer executable (typically in Program Files/RealPlayer or /Applications/RealPlayer.app), select Properties > Details to view the File Version. Alternatively, open RealPlayer and check Help > About RealPlayer.
    Affected if The version displayed is <= 12.0.0.1701, = 7.0, = 8.0, = 10.0, = 10.0.0.305, = 10.0.0.331, = 10.1, = 12.0.0.1569, <= 14.0.7, = 4, = 5, or = 6
  3. Confirm the platform and full version number
    Determine if the system is Windows or Mac. For Windows, verify the version is prior to 15.0.0. For Mac, verify the version is prior to 12.0.0.1703.
    Affected if Windows version is below 15.0.0 OR Mac version is below 12.0.0.1703
  4. Verify RealVideo renderer component is present
    Attempt to play a RealVideo file (.rv, .rm, .rmvb extension) or check RealPlayer's codec/component status. The vulnerability exists in the RealVideo renderer specifically.
    Affected if RealVideo files can be played or the RealVideo codec component is listed as installed

If RealPlayer is installed and the version falls within the affected ranges (any version <= 12.0.0.1701, = 7.0/8.0/10.0/10.0.0.305/10.0.0.331/10.1/12.0.0.1569/4/5/6 on Windows, or < 12.0.0.1703 on Mac, or <= 14.0.7), the system is affected by CVE-2011-4245.

dbcve · scoped
Upgrade available Upgrade to a release after 14.0.7
Interim mitigation

Upgrade to RealPlayer 15.0.0+ (Windows) or 12.0.0.1703+ (Mac). If immediate upgrade is not feasible, disable RealVideo playback functionality and restrict network exposure to untrusted content sources.

Recommended fix High confidence
