CVE-2013-4207 is a buffer overflow vulnerability in PuTTY versions prior to 0.63, affecting both PuTTY and Simon Tatham PuTTY. A remote SSH server can exploit this by sending a malformed DSA signature, leading to a denial of service (crash) due to improper handling of modular inverse computations and a subsequent division by zero in the bignum functionality. This vulnerability has a CVSS score of 4.3 (Medium), indicating a network-based attack with medium complexity and a potential impact of partial availability loss. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
