| CVE | Vendors | Products | Updated | CVSS v2 | CVSS v3 |
|---|---|---|---|---|---|
| CVE-2013-4852 | 5 Debian, Opensuse, Putty and 2 more | 5 Debian Linux, Opensuse, Putty and 2 more | 2026-06-16 | 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-2013-4208 | 2 Putty, Simon Tatham | 2 Putty, Putty | 2026-06-16 | 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-2013-4207 | 2 Putty, Simon Tatham | 2 Putty, Putty | 2026-06-16 | 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-2013-4206 | 2 Putty, Simon Tatham | 2 Putty, Putty | 2026-06-16 | 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-2011-4607 | 1 Putty | 1 Putty | 2026-06-16 | 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-2006-7162 | 1 Putty | 1 Putty | 2026-06-16 | 1.9 LOW | N/A |
| PuTTY 0.59 and earlier uses weak file permissions for (1) ppk files containing private keys generated by puttygen and (2) session logs created by putty, which allows local users to gain sensitive information by reading these files. | |||||
| CVE-2005-0467 | 1 Putty | 1 Putty | 2026-06-16 | 7.5 HIGH | 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-2004-1440 | 1 Putty | 1 Putty | 2026-06-16 | 7.5 HIGH | N/A |
| 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-2004-1008 | 2 Putty, Tortoisecvs | 2 Putty, Tortoisecvs | 2026-06-16 | 10.0 HIGH | N/A |
| 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-2003-0069 | 1 Putty | 1 Putty | 2026-06-16 | 7.5 HIGH | N/A |
| 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-2003-0048 | 1 Putty | 1 Putty | 2026-06-16 | 4.6 MEDIUM | N/A |
| PuTTY 0.53b and earlier does not clear logon credentials from memory, including plaintext passwords, which could allow attackers with access to memory to steal the SSH credentials. | |||||
| CVE-2002-1360 | 7 Cisco, Fissh, Intersoft and 4 more | 7 Ios, Ssh Client, Securenetterm and 4 more | 2026-06-16 | 10.0 HIGH | N/A |
| 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 | 7 Cisco, Fissh, Intersoft and 4 more | 7 Ios, Ssh Client, Securenetterm and 4 more | 2026-06-16 | 10.0 HIGH | N/A |
| 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 | 7 Cisco, Fissh, Intersoft and 4 more | 7 Ios, Ssh Client, Securenetterm and 4 more | 2026-06-16 | 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. | |||||
| CVE-2002-1357 | 7 Cisco, Fissh, Intersoft and 4 more | 7 Ios, Ssh Client, Securenetterm and 4 more | 2026-06-16 | 10.0 HIGH | N/A |
| 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. | |||||
| CVE-2000-0476 | 4 Michael Jennings, Putty, Rxvt and 1 more | 4 Eterm, Putty, Rxvt and 1 more | 2026-06-16 | 5.0 MEDIUM | N/A |
| xterm, Eterm, and rxvt allow an attacker to cause a denial of service by embedding certain escape characters which force the window to be resized. | |||||
