CVE Severity Published▾ Status Exploitation Description
CVE-2021-36367 High 2021-07-09 Not applicable No public exploit 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 High 2021-05-21 Not applicable No public exploit 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-2019-17069 High 2019-10-01 Outside Waratek scope No public exploit 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 High 2019-10-01 Not applicable No public exploit PuTTY before 0.73 mishandles the "bracketed paste mode" protection mechanism, which may allow a session to be affected by malicious clipboard content.
CVE-2019-9897 High 2019-03-21 Outside Waratek scope No public exploit Multiple denial-of-service attacks that can be triggered by writing to the terminal exist in PuTTY versions before 0.71.
CVE-2019-9896 High 2019-03-21 Not applicable Proof of concept only 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-2019-9894 High 2019-03-21 Outside Waratek scope No public exploit A remotely triggerable memory overwrite in RSA key exchange in PuTTY before 0.71 can occur before host key verification.
CVE-2016-6167 High 2017-01-30 Not applicable No public exploit 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-2005-0467 High 2005-02-21 Not applicable No public exploit 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-2004-1008 High 2005-01-10 Not applicable No public exploit Integer signedness error in the ssh2_rdpkt function in PuTTY before 0.56 allows remote attackers to execute arbitrary code via a SSH2_MSG_DEBUG packet with a modified stringlen parameter, which leads to a buffer overflow.
CVE-2004-1440 High 2004-12-31 Not applicable No public exploit Multiple heap-based buffer overflows in the modpow function in PuTTY before 0.55 allow (1) remote attackers to execute arbitrary code via an SSH2 packet with a base argument that is larger than the mod argument, which causes the modpow function to write memory before the beginning of its buffer, and (2) remote malicious servers to cause a denial of service (client crash) and possibly execute arbitrary code via a large bignum during authentication.
CVE-2003-0069 High 2003-03-18 Not applicable No public exploit The PuTTY terminal emulator 0.53 allows attackers to modify the window title via a certain character escape sequence and then insert it back to the command line in the user's terminal, e.g. when the user views a file containing the malicious sequence, which could allow the attacker to execute arbitrary commands.
CVE-2002-1360 High 2002-12-23 Not applicable No public exploit Multiple SSH2 servers and clients do not properly handle strings with null characters in them when the string length is specified by a length field, which could allow remote attackers to cause a denial of service or possibly execute arbitrary code due to interactions with the use of null-terminated strings as implemented using languages such as C, as demonstrated by the SSHredder SSH protocol test suite.
CVE-2002-1359 High 2002-12-23 Not applicable Working exploit published Multiple SSH2 servers and clients do not properly handle large packets or large fields, which may allow remote attackers to cause a denial of service or possibly execute arbitrary code via buffer overflow attacks, as demonstrated by the SSHredder SSH protocol test suite.
CVE-2002-1358 High 2002-12-23 Not applicable No public exploit 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.
CVE-2002-1357 High 2002-12-23 Not applicable No public exploit Multiple SSH2 servers and clients do not properly handle packets or data elements with incorrect length specifiers, 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.
