CVE-2010-4375
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 · uneditedHeap-based buffer overflow in RealNetworks RealPlayer 11.0 through 11.1, Mac RealPlayer 11.0 through 11.1, Linux RealPlayer 11.0.2.1744, and possibly HelixPlayer 1.0.6 and other versions, allows remote attackers to execute arbitrary code via malformed multi-rate data in an 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 confidenceHeap-based buffer overflow vulnerability in RealNetworks RealPlayer (versions 11.0-11.1 on Windows/Mac, 11.0.2.1744 on Linux) and possibly HelixPlayer. The flaw exists in the parsing of malformed multi-rate data within audio streams, allowing remote attackers to execute arbitrary code via specially crafted audio files.

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.
-
Check if RealPlayer is installedOn Windows, check Program Files for RealPlayer folder or look in Add/Remove Programs. On Linux, check /usr/bin/realplay or similar paths. On Mac, check /Applications for RealPlayer.Affected if RealPlayer is installed on the system
-
Determine installed RealPlayer versionLaunch RealPlayer and navigate to Help > About RealPlayer, or right-click the executable and view Properties > Details for version information.Affected if The version matches any of these: 11.0, 11.0.1, 11.0.2, 11.0.3, 11.0.4, 11.0.5, 11.1 (Windows/Mac) or 11.0.2.1744 (Linux)
-
Check for HelixPlayer installationSearch for helixplayer executable in common locations such as /usr/bin/ on Linux or Program Files on Windows.Affected if HelixPlayer is installed (it may also be affected by this vulnerability)
-
Verify audio file handling is enabledCheck RealPlayer settings under Tools > Options or Preferences to confirm audio stream handling and multi-rate audio parsing features are enabled.Affected if RealPlayer is configured to automatically handle or parse audio streams from files
The system is affected if RealPlayer version 11.0 through 11.1 (Windows/Mac) or 11.0.2.1744 (Linux), or HelixPlayer, is installed and configured to parse audio files.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate to a patched version of RealPlayer beyond 11.1, or replace with an alternative media player. Disable automatic handling of audio streams from untrusted sources until the patch is applied.
