PuTTY 0.84 has been released addressing several minor security flaws, including crashes during SSH key exchange caused by incorrect elliptic curve handling and a Telnet prompt spoofing issue related to proxy authentication. These vulnerabilities, exploitable by malicious servers or man-in-the-middle attackers, primarily result in denial-of-service conditions, and users are advised to upgrade promptly for improved robustness and security.
