What is CVE-2013-4208?

A vulnerability in the rsa_verify function of PuTTY prior to version 0.63 has been identified, where sensitive process memory is not properly cleared after use. This could potentially leave private RSA and DSA keys exposed in memory, enabling local users to access these sensitive keys. Such a lapse in memory management poses a significant risk to the security of cryptographic operations performed within PuTTY, necessitating immediate attention and remediation.
