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.
CVE-2017-6542 3 Opensuse, Opensuse Project, Putty 3 Leap, Leap, Putty 2024-11-21 N/A
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-2016-6167 1 Putty 1 Putty 2024-11-21 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-2015-2157 5 Debian, Fedoraproject, Opensuse and 2 more 5 Debian Linux, Fedora, Opensuse and 2 more 2024-11-21 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-2013-4852 5 Debian, Opensuse, Putty and 2 more 5 Debian Linux, Opensuse, Putty and 2 more 2024-11-21 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 2024-11-21 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 2024-11-21 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 2024-11-21 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 2024-11-21 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 2024-11-21 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.
