2019-03-21 CVE-2019-9897 Multiple denial-of-service attacks that can be triggered by writing to the terminal exist in PuTTY versions before 0.71. Debian_linux, Fedora, Oncommand_unified_manager, Leap, Putty 7.5
2019-03-21 CVE-2019-9898 Potential recycling of random numbers used in cryptography exists within PuTTY before 0.71. Debian_linux, Fedora, Oncommand_unified_manager, Leap, Putty 9.8
2020-06-29 CVE-2020-14002 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). Fedora, Oncommand_unified_manager_core_package, Putty 5.9
2017-01-30 CVE-2016-6167 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. Putty 7.8
2019-03-21 CVE-2019-9896 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. Backports_sle, Leap, Putty 7.8
2019-10-01 CVE-2019-17069 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. Oncommand_unified_manager_core_package, Leap, Putty 7.5
2013-08-19 CVE-2013-4852 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. Debian_linux, Opensuse, Putty, Putty, Winscp N/A
2013-08-19 CVE-2013-4207 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. Putty, Putty N/A
2013-08-19 CVE-2013-4206 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. Putty, Putty N/A
2021-05-21 CVE-2021-33500 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. Putty 7.5
