CVE-2005-4817

CVE-2005-4817 describes a format string vulnerability in Textbased MSN Client (TMSNC) versions prior to 0.2.5, specifically within the ui.c component. An unauthenticated attacker can exploit this by injecting format strings into the wprintw function, leading to a denial of service and potentially arbitrary code execution. With a CVSS score of 7.5, this vulnerability is considered high severity due to its network-based attack vector and low attack complexity, allowing for partial impact on confidentiality, integrity, and availability. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage, indicating it is not a widely targeted or discussed vulnerability.
