Heap-based buffer overflow in RealNetworks RealPlayer 11.0 through 11.1, RealPlayer SP 1.0 through 1.1.5, and RealPlayer Enterprise 2.1.2 and 2.1.3 allows remote attackers to execute arbitrary code via a crafted value in an unspecified header field in an RMX file.

Security readout for executives and security teams

This is a legacy RealPlayer flaw where a malicious RMX media file could crash or take control of a vulnerable player. The business risk is highest where old RealPlayer or RealPlayer Enterprise remains installed on desktops or kiosk-like systems. Exposure is likely limited to legacy endpoints that still have the listed RealNetworks products installed and can open RMX files from email, web, shares, or removable media. Treat as a targeted legacy-software cleanup issue. Prioritize discovery and removal on user workstations, shared desktops, and systems exposed to untrusted media files. Mitigation focus: Inventory endpoints for the listed RealPlayer and RealPlayer Enterprise versions.; Check RealNetworks advisory for vendor-approved update, removal, or configuration guidance.; Remove vulnerable RealPlayer installations where there is no current business requirement..
