Simon Tatham reports:

+
When PuTTY has sensitive data in memory and has no further need for + it, it should wipe the data out of its memory, in case malware later + gains access to the PuTTY process or the memory is swapped out to + disk or written into a crash dump file. An obvious example of this + is the password typed during SSH login; other examples include + obsolete session keys, public-key passphrases, and the private + halves of public keys.
+
PuTTY 0.63 and earlier versions, after loading a private key + from a disk file, mistakenly leak a memory buffer containing a + copy of the private key, in the function ssh2_load_userkey. The + companion function ssh2_save_userkey (only called by PuTTYgen) can + also leak a copy, but only in the case where the file it tried to + save to could not be created.
