Heap-based buffer overflow in RealNetworks RealPlayer 11.0 through 11.1, RealPlayer SP 1.0 through 1.1.1, Mac RealPlayer 11.0 through 11.1, and Linux RealPlayer 11.0.2.1744 allows remote attackers to execute arbitrary code via a large Screen Width value in the Screen Descriptor header of a GIF87a file in an RTSP stream.

Security readout for executives and security teams

CVE-2010-4376 is a RealPlayer memory corruption flaw that could let an attacker run code when a vulnerable player processes a malicious RTSP media stream. The issue concerns legacy RealPlayer versions from around 2010. Business urgency depends on whether those versions still exist in the environment. Exposure is likely limited to endpoints or servers where the listed legacy RealPlayer versions remain installed and are able to open RTSP streams. The provided affected-product metadata is incomplete, but the CVE description names specific RealPlayer product families and versions. Prioritize as a targeted legacy-software risk. If RealPlayer is absent, business impact is minimal. If affected versions remain installed, remediation should be prompt because the stated impact is arbitrary code execution through media handling. Mitigation focus: Inventory systems for the affected RealPlayer versions named in the CVE description.; Apply RealNetworks guidance from the cited security advisory where applicable.; Remove unsupported or unnecessary RealPlayer installations from managed endpoints..
