SUSE 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...

SUSE 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...

SUSE 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...

SUSE 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...

SUSE CVE-2015-2157

The 1 ssh2loaduserkey and 2 ssh2saveuserkey 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...

SUSE CVE-2015-5309

Integer overflow in the terminal emulator in PuTTY before 0.66 allows remote attackers to cause a denial of service memory corruption or possibly execute arbitrary code via an ECH erase characters escape sequence with a large parameter value, which triggers a buffer underflow...

SUSE CVE-2016-2563

Stack-based buffer overflow in the SCP command-line utility in PuTTY before 0.67 and KiTTY 0.66.6.3 and earlier allows remote servers to cause a denial of service stack memory corruption or execute arbitrary code via a crafted SCP-SINK file-size response to an SCP download request...

SUSE CVE-2016-6167

Multiple untrusted search path vulnerabilities in Putty beta 0.67 allow local users to execute arbitrary code and conduct DLL hijacking attacks via a Trojan horse 1 UxTheme.dll or 2 ntmarta.dll file in the current working directory...

SUSE CVE-2017-6542

The sshagentchanneldata function in PuTTY before 0.68 allows remote attackers to have unspecified impact via a large length value in an agent protocol message and leveraging the ability to connect to the Unix-domain socket representing the forwarded agent connection, which trigger a buffer overfl...

SUSE CVE-2019-9895

In PuTTY versions before 0.71 on Unix, a remotely triggerable buffer overflow exists in any kind of server-to-client forwarding...

SUSE CVE-2019-9896

In PuTTY versions before 0.71 on Windows, local attackers could hijack the application by putting a malicious help file in the same directory as the executable...

SUSE CVE-2019-9894

A remotely triggerable memory overwrite in RSA key exchange in PuTTY before 0.71 can occur before host key verification...

SUSE CVE-2019-9898

SUSE CVE-2019-9897

Multiple denial-of-service attacks that can be triggered by writing to the terminal exist in PuTTY versions before 0.71...

SUSE CVE-2019-17067

PuTTY before 0.73 on Windows improperly opens port-forwarding listening sockets, which allows attackers to listen on the same port to steal an incoming connection...

SUSE CVE-2019-17068

PuTTY before 0.73 mishandles the "bracketed paste mode" protection mechanism, which may allow a session to be affected by malicious clipboard content...

SUSE CVE-2019-17069

PuTTY before 0.73 might allow remote SSH-1 servers to cause a denial of service by accessing freed memory locations via an SSH1MSGDISCONNECT message...

SUSE CVE-2020-14002

PuTTY 0.68 through 0.73 has an Observable Discrepancy leading to an information leak in the algorithm negotiation. This allows man-in-the-middle attackers to target initial connection attempts where no host key for the server has been cached by the client...
