CVE-2010-4375

CVE-2010-4375 is a critical heap-based buffer overflow vulnerability affecting RealNetworks RealPlayer 11.0-11.1, Mac RealPlayer 11.0-11.1, and Linux RealPlayer 11.0.2.1744, potentially extending to HelixPlayer 1.0.6. This flaw allows remote attackers to execute arbitrary code by crafting malformed multi-rate data within an audio stream. With a CVSS score of 9.3, it presents a severe risk due to its network-based attack vector, medium attack complexity, and complete compromise of confidentiality, integrity, and availability. Despite its high severity, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
