CVE-2009-3871

25
FAUCET Score

CVE-2009-3871 describes a critical heap-based buffer overflow in the setBytePixels function within the Abstract Window Toolkit (AWT) of Sun Java SE JDK and JRE versions 5.0 before Update 22 and 6 before Update 17, as well as older SDK/JRE 1.3.x and 1.4.x branches. This vulnerability allows remote attackers to execute arbitrary code on affected systems through specially crafted arguments. With a CVSS score of 9.3, it represents a high-severity threat due to its network-based attack vector, medium attack complexity, and complete compromise of confidentiality, integrity, and availability. Despite its age and 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 a currently prioritized threat.
