FAUCET Score

CVE-2007-2966 describes a buffer overflow vulnerability in the LHA decompression component of F-Secure anti-virus products for Windows and Linux, affecting versions prior to 20070529. This flaw allows remote attackers to execute arbitrary code or cause a denial of service through a specially crafted LHA archive. With a CVSS score of 7.5, it is considered highly severe, requiring no authentication and low attack complexity to achieve partial impact on confidentiality, integrity, and availability. While no active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion has been identified, the vulnerability's nature poses a considerable risk if exploited.
