CVE-2005-0467 1 Putty 1 Putty 2025-04-03 N/A
Multiple integer overflows in the (1) sftp_pkt_getstring and (2) fxp_readdir_recv functions in the PSFTP and PSCP clients for PuTTY 0.56, and possibly earlier versions, allow remote malicious web sites to execute arbitrary code via SFTP responses that corrupt the heap after insufficient memory has been allocated.
CVE-2021-36367 1 Putty 1 Putty 2024-11-21 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 2024-11-21 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-2020-14002 3 Fedoraproject, Netapp, Putty 3 Fedora, Oncommand Unified Manager Core Package, Putty 2024-11-21 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-2019-9898 5 Debian, Fedoraproject, Netapp and 2 more 5 Debian Linux, Fedora, Oncommand Unified Manager and 2 more 2024-11-21 N/A
Potential recycling of random numbers used in cryptography exists within PuTTY before 0.71.
CVE-2019-9897 5 Debian, Fedoraproject, Netapp and 2 more 5 Debian Linux, Fedora, Oncommand Unified Manager and 2 more 2024-11-21 N/A
Multiple denial-of-service attacks that can be triggered by writing to the terminal exist in PuTTY versions before 0.71.
CVE-2019-9896 3 Microsoft, Opensuse, Putty 4 Windows, Backports Sle, Leap and 1 more 2024-11-21 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-2019-9895 3 Fedoraproject, Opengroup, Putty 3 Fedora, Unix, Putty 2024-11-21 N/A
In PuTTY versions before 0.71 on Unix, a remotely triggerable buffer overflow exists in any kind of server-to-client forwarding.
CVE-2019-9894 5 Debian, Fedoraproject, Netapp and 2 more 5 Debian Linux, Fedora, Oncommand Unified Manager and 2 more 2024-11-21 N/A
A remotely triggerable memory overwrite in RSA key exchange in PuTTY before 0.71 can occur before host key verification.
CVE-2019-17069 3 Netapp, Opensuse, Putty 3 Oncommand Unified Manager Core Package, Leap, Putty 2024-11-21 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-2019-17068 2 Opensuse, Putty 2 Leap, Putty 2024-11-21 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-2019-17067 2 Microsoft, Putty 2 Windows, Putty 2024-11-21 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.
