CVE-2010-4394

27
FAUCET Score

CVE-2010-4394 describes a heap-based buffer overflow vulnerability in RealNetworks RealPlayer versions 11.0 through 11.1 and RealPlayer SP versions 1.0 through 1.1.5. This flaw allows remote web servers to execute arbitrary code by sending an overly long Server header in an HTTP response while a RealPix file is being parsed. With a CVSS score of 9.3, this vulnerability is critical, requiring medium attack complexity but potentially leading to 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, suggesting it is not widely targeted.
