CVE-2013-4207
PuTTY before 0.63 is affected by CVE-2013-4207 due to a heap-based buffer overflow in sshbn.c (modular arithmetic during DSA signature handling). The overflow can crash a remote SSH server and is triggered by an invalid DSA signature during the bignum division-by-zero path. This is distinct from ...
CVE-2013-4208
The rsaverify 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-2013-4206
Heap-based buffer underflow in the modmul function in sshbn.c in PuTTY before 0.63 allows remote SSH servers to cause a denial of service crash and possibly trigger memory corruption or code execution via a crafted DSA signature, which is not properly handled when performing certain bit-shifting...
CVE-2013-4207
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 division by zero by the bignum functionality, a differe...

PuTTY 0.52 to 0.62 Multiple Vulnerabilities
The remote host has an installation of PuTTY version 0.52 or greater but earlier than version 0.63. As such, it is reportedly affected by the following vulnerabilities : - An overflow error exists in the function 'modmul' in the file 'putty/sshbn.c' that could allow heap corruption when handling...
FileZilla Client < 3.7.2 SFTP Integer Overflow
The version of FileZilla Client on the remote host is a version prior to 3.7.2. As such, it is affected by an integer overflow vulnerability that exists in the 'getstring' function from PuTTY used to handle SFTP. This can lead to a heap overflow during the SSH handshake prior to authentication, d...
