CVE-2013-4852

Integer overflow in PuTTY 0.62 and earlier, WinSCP before 5.1.6, and other products that use PuTTY allows remote SSH servers to cause a denial of service crash and possibly execute arbitrary code in certain applications that use PuTTY via a negative size value in an RSA key signature during the S...

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-2013-4208

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-2013-4207

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...

CVE-2013-4206

PuTTY before 0.63 is affected by CVE-2013-4206 due to a heap-based buffer underflow in modmul (sshbn.c). The vulnerability allows remote SSH servers to cause a denial of service (crash) and possibly memory corruption or code execution via a crafted DSA signature, related to improper handling duri...

CVE-2013-4208

CVE-2013-4208 affects PuTTY up to version 0.63 where rsa_verify mishandles sensitive memory and does not free certain structures, potentially exposing private RSA/DSA keys. Several advisories note updates that merge PuTTY fixes into downstream projects (e.g., FileZilla 3.7.3 and Fedora/OpenSUSE a...

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 ...

Debian DSA-2736-1 : putty - several vulnerabilities

Several vulnerabilities where discovered in PuTTY, a Telnet/SSH client for X. The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2013-4206 Mark Wooding discovered a heap-corrupting buffer underrun bug in the modmul function which performs modular...

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...

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...
