25
FAUCET Score

CVE-2005-3265 describes a critical buffer overflow vulnerability in Skype for Windows versions 1.1.x.0 through 1.4.x.83. This flaw allows remote attackers to execute arbitrary code by exploiting malformed callto:// or skype:// links, or a non-standard VCARD, potentially stemming from an error in the SysUtils.WideFmtStr Delphi routine. With a CVSS score of 9.3, it represents a severe risk, enabling complete compromise of confidentiality, integrity, and availability with medium attack complexity and no authentication required. Despite its high severity and EPSS score, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
