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 checksWork through these to decide whether this CVE applies to you.
-
Verify RealPlayer installationCheck if RealPlayer is installed by looking for the RealPlayer executable in common installation directories or by searching for RealPlayer in the system program files.Affected if RealPlayer is found on the system
-
Identify the installed RealPlayer versionRight-click the RealPlayer executable, select Properties, and view the Version tab to find the product version. Alternatively, open RealPlayer and navigate to Help > About RealPlayer.Affected if The version matches 11.0, 11.1, 14.0.0, 14.0.1, 14.0.2, 14.0.3, 14.0.4, 14.0.5 for RealPlayer, or 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 for RealPlayer SP
-
Locate the vulnerable qcpfformat.dll componentSearch for qcpfformat.dll within the RealPlayer installation directory. This DLL handles QCP media file parsing.Affected if qcpfformat.dll is present in the RealPlayer installation folder, indicating the vulnerable component exists.
If RealPlayer or RealPlayer SP is installed with a version matching the affected list and the qcpfformat.dll component is present, the system is vulnerable when processing QCP media files.
