CVE-2009-4356

25
FAUCET Score

CVE-2009-4356 describes multiple integer overflow vulnerabilities in the jpeg.w5s and png.w5s filters of Winamp versions prior to 5.57, allowing remote attackers to execute arbitrary code through specially crafted JPEG or PNG data embedded in MP3 files. This vulnerability carries a critical CVSS score of 9.3, indicating a high potential for complete compromise of confidentiality, integrity, and availability with medium attack complexity and no authentication required. While no public exploit intelligence like Metasploit modules or ExploitDB entries exist, and there's no evidence of active exploitation, the high FAUCET Risk Score of 82/100 suggests significant inherent risk. Community discussion and media coverage for this CVE are minimal, which is typical for a large percentage of vulnerabilities.
