FAUCET Score

CVE-2007-1680 describes a stack-based buffer overflow vulnerability in the AudioConf ActiveX control (yacscom.dll) within Yahoo! Messenger versions prior to 20070313. This flaw allows remote attackers to execute arbitrary code by supplying excessively long values to the socksHostname and hostname properties. With a CVSS score of 9.3, this vulnerability is critical, indicating a network-based attack with medium complexity that can lead to complete compromise of confidentiality, integrity, and availability. While no active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion has been observed, the high FAUCET Risk Score of 97/100 and above-average EPSS score suggest a notable potential for impact.
