|---|---|---|---|---|---|
| CVE-2020-14002 | 3 Fedoraproject, Netapp, Putty | 3 Fedora, Oncommand Unified Manager Core Package, Putty | 2022-05-03 | 4.3 MEDIUM | 5.9 MEDIUM |
| 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). | |||||
| CVE-2016-6167 | 1 Putty | 1 Putty | 2022-04-30 | 4.4 MEDIUM | 7.8 HIGH |
| 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. | |||||
| CVE-2019-9896 | 3 Microsoft, Opensuse, Putty | 4 Windows, Backports Sle, Leap and 1 more | 2022-04-05 | 4.6 MEDIUM | 7.8 HIGH |
| 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. | |||||
| CVE-2019-17069 | 3 Netapp, Opensuse, Putty | 3 Oncommand Unified Manager Core Package, Leap, Putty | 2022-03-31 | 5.0 MEDIUM | 7.5 HIGH |
| PuTTY before 0.73 might allow remote SSH-1 servers to cause a denial of service by accessing freed memory locations via an SSH1_MSG_DISCONNECT message. | |||||
| CVE-2013-4852 | 5 Debian, Opensuse, Putty and 2 more | 5 Debian Linux, Opensuse, Putty and 2 more | 2021-08-06 | 6.8 MEDIUM | N/A |
| 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 SSH handshake, which triggers a heap-based buffer overflow. | |||||
| CVE-2013-4206 | 2 Putty, Simon Tatham | 2 Putty, Putty | 2021-08-06 | 6.8 MEDIUM | N/A |
| 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 operations during modular multiplication. | |||||
| CVE-2013-4207 | 2 Putty, Simon Tatham | 2 Putty, Putty | 2021-08-06 | 4.3 MEDIUM | N/A |
| 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 different vulnerability than CVE-2013-4206. | |||||
| CVE-2019-9897 | 5 Debian, Fedoraproject, Netapp and 2 more | 5 Debian Linux, Fedora, Oncommand Unified Manager and 2 more | 2021-07-21 | 5.0 MEDIUM | 7.5 HIGH |
| Multiple denial-of-service attacks that can be triggered by writing to the terminal exist in PuTTY versions before 0.71. | |||||
| CVE-2019-9898 | 5 Debian, Fedoraproject, Netapp and 2 more | 5 Debian Linux, Fedora, Oncommand Unified Manager and 2 more | 2021-07-21 | 7.5 HIGH | 9.8 CRITICAL |
| Potential recycling of random numbers used in cryptography exists within PuTTY before 0.71. | |||||
| CVE-2021-36367 | 1 Putty | 1 Putty | 2021-07-14 | 5.8 MEDIUM | 8.1 HIGH |
| PuTTY through 0.75 proceeds with establishing an SSH session even if it has never sent a substantive authentication response. This makes it easier for an attacker-controlled SSH server to present a later spoofed authentication prompt (that the attacker can use to capture credential data, and use that data for purposes that are undesired by the client user). | |||||
| CVE-2021-33500 | 2 Microsoft, Putty | 2 Windows, Putty | 2021-05-27 | 5.0 MEDIUM | 7.5 HIGH |
| PuTTY before 0.75 on Windows allows remote servers to cause a denial of service (Windows GUI hang) by telling the PuTTY window to change its title repeatedly at high speed, which results in many SetWindowTextA or SetWindowTextW calls. NOTE: the same attack methodology may affect some OS-level GUIs on Linux or other platforms for similar reasons. | |||||
| CVE-2019-17067 | 2 Microsoft, Putty | 2 Windows, Putty | 2019-11-26 | 7.5 HIGH | 9.8 CRITICAL |
| 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. | |||||
| CVE-2019-17068 | 2 Opensuse, Putty | 2 Leap, Putty | 2019-11-26 | 5.0 MEDIUM | 7.5 HIGH |
| PuTTY before 0.73 mishandles the "bracketed paste mode" protection mechanism, which may allow a session to be affected by malicious clipboard content. | |||||
| CVE-2019-9894 | 5 Debian, Fedoraproject, Netapp and 2 more | 5 Debian Linux, Fedora, Oncommand Unified Manager and 2 more | 2019-04-26 | 6.4 MEDIUM | 7.5 HIGH |
| A remotely triggerable memory overwrite in RSA key exchange in PuTTY before 0.71 can occur before host key verification. | |||||
| CVE-2019-9895 | 3 Fedoraproject, Opengroup, Putty | 3 Fedora, Unix, Putty | 2019-04-04 | 7.5 HIGH | 9.8 CRITICAL |
| In PuTTY versions before 0.71 on Unix, a remotely triggerable buffer overflow exists in any kind of server-to-client forwarding. | |||||
| CVE-2015-2157 | 5 Debian, Fedoraproject, Opensuse and 2 more | 5 Debian Linux, Fedora, Opensuse and 2 more | 2019-03-21 | 2.1 LOW | N/A |
| 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-2011-4607 | 1 Putty | 1 Putty | 2019-03-21 | 2.1 LOW | N/A |
| PuTTY 0.59 through 0.61 does not clear sensitive process memory when managing user replies that occur during keyboard-interactive authentication, which might allow local users to read login passwords by obtaining access to the process' memory. | |||||
| CVE-2013-4208 | 2 Putty, Simon Tatham | 2 Putty, Putty | 2019-03-21 | 2.1 LOW | N/A |
| 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-2017-6542 | 3 Opensuse, Opensuse Project, Putty | 3 Leap, Leap, Putty | 2018-10-30 | 7.5 HIGH | 9.8 CRITICAL |
| The ssh_agent_channel_data 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 overflow. | |||||
| CVE-2002-1358 | 7 Cisco, Fissh, Intersoft and 4 more | 7 Ios, Ssh Client, Securenetterm and 4 more | 2017-10-10 | 10.0 HIGH | N/A |
| Multiple SSH2 servers and clients do not properly handle lists with empty elements or strings, which may allow remote attackers to cause a denial of service or possibly execute arbitrary code, as demonstrated by the SSHredder SSH protocol test suite. | |||||
