The (1) ssh2_load_userkey and (2) ssh2_save_userkey functions in PuTTY 0.51 through 0.63 do not properly wipe SSH-2 private keys from memory, which allows local users to obtain sensitive information by reading the memory.
CVE-2013-4207 2 Simon Tatham, Putty 2 Putty, Putty 2019-03-21 4.3
Buffer overflow in sshbn.c in PuTTY before 0.63 allows remote SSH servers to cause a denial of service (crash) via an invalid DSA signature that is not properly handled during computation of a modular inverse and triggers the overflow during a...
CVE-2013-4208 2 Simon Tatham, Putty 2 Putty, Putty 2019-03-21 2.1
The rsa_verify function in PuTTY before 0.63 (1) does not clear sensitive process memory after use and (2) does not free certain structures containing sensitive process memory, which might allow local users to discover private RSA and DSA keys.
CVE-2013-4852 6 Debian, Simon Tatham, Novell and 3 more 6 Debian Linux, Winscp, Putty and 3 more 2019-03-21 6.8
