CVE-2004-1440 describes multiple heap-based buffer overflows in the modpow function of PuTTY versions prior to 0.55. This vulnerability allows remote attackers to execute arbitrary code or cause a denial of service (client crash) through specially crafted SSH2 packets or large bignums during authentication. With a CVSS score of 7.5, it is considered highly severe due to its network attack vector, low access complexity, and potential for partial compromise of confidentiality, integrity, and availability. While no public exploit code (Metasploit, Nuclei, ExploitDB) is listed, the vulnerability has garnered significant community discussion, indicating awareness and potential for exploitation.
