|---|---|---|---|---|---|
| CVE-2016-10011 | 1 Openbsd | 1 Openssh | 2022-12-13 | 2.1 LOW | 5.5 MEDIUM |
| authfile.c in sshd in OpenSSH before 7.4 does not properly consider the effects of realloc on buffer contents, which might allow local users to obtain sensitive private-key information by leveraging access to a privilege-separated child process. | |||||
| CVE-2015-5352 | 1 Openbsd | 1 Openssh | 2022-12-13 | 4.3 MEDIUM | N/A |
| The x11_open_helper function in channels.c in ssh in OpenSSH before 6.9, when ForwardX11Trusted mode is not used, lacks a check of the refusal deadline for X connections, which makes it easier for remote attackers to bypass intended access restrictions via a connection outside of the permitted time window. | |||||
| CVE-2016-0777 | 5 Apple, Hp, Openbsd and 2 more | 7 Mac Os X, Remote Device Access Virtual Customer Access System, Openssh and 4 more | 2022-12-13 | 4.0 MEDIUM | 6.5 MEDIUM |
| The resend_bytes function in roaming_common.c in the client in OpenSSH 5.x, 6.x, and 7.x before 7.1p2 allows remote servers to obtain sensitive information from process memory by requesting transmission of an entire buffer, as demonstrated by reading a private key. | |||||
| CVE-2019-6111 | 5 Canonical, Debian, Openbsd and 2 more | 5 Ubuntu Linux, Debian Linux, Openssh and 2 more | 2022-12-13 | 5.8 MEDIUM | 5.9 MEDIUM |
| An issue was discovered in OpenSSH 7.9. Due to the scp implementation being derived from 1983 rcp, the server chooses which files/directories are sent to the client. However, the scp client only performs cursory validation of the object name returned (only directory traversal attacks are prevented). A malicious scp server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the scp client target directory. If recursive operation (-r) is performed, the server can manipulate subdirectories as well (for example, to overwrite the .ssh/authorized_keys file). | |||||
| CVE-2003-1562 | 1 Openbsd | 1 Openssh | 2022-12-13 | 7.6 HIGH | N/A |
| sshd in OpenSSH 3.6.1p2 and earlier, when PermitRootLogin is disabled and using PAM keyboard-interactive authentication, does not insert a delay after a root login attempt with the correct password, which makes it easier for remote attackers to use timing differences to determine if the password step of a multi-step authentication is successful, a different vulnerability than CVE-2003-0190. | |||||
| CVE-2015-5600 | 1 Openbsd | 1 Openssh | 2022-12-13 | 8.5 HIGH | N/A |
| The kbdint_next_device function in auth2-chall.c in sshd in OpenSSH through 6.9 does not properly restrict the processing of keyboard-interactive devices within a single connection, which makes it easier for remote attackers to conduct brute-force attacks or cause a denial of service (CPU consumption) via a long and duplicative list in the ssh -oKbdInteractiveDevices option, as demonstrated by a modified client that provides a different password for each pam element on this list. | |||||
| CVE-2016-6210 | 1 Openbsd | 1 Openssh | 2022-12-13 | 4.3 MEDIUM | 5.9 MEDIUM |
| sshd in OpenSSH before 7.3, when SHA256 or SHA512 are used for user password hashing, uses BLOWFISH hashing on a static password when the username does not exist, which allows remote attackers to enumerate users by leveraging the timing difference between responses when a large password is provided. | |||||
| CVE-2015-8325 | 3 Canonical, Debian, Openbsd | 5 Ubuntu Core, Ubuntu Linux, Ubuntu Touch and 2 more | 2022-12-13 | 7.2 HIGH | 7.8 HIGH |
| The do_setup_env function in session.c in sshd in OpenSSH through 7.2p2, when the UseLogin feature is enabled and PAM is configured to read .pam_environment files in user home directories, allows local users to gain privileges by triggering a crafted environment for the /bin/login program, as demonstrated by an LD_PRELOAD environment variable. | |||||
| CVE-2016-0778 | 5 Apple, Hp, Openbsd and 2 more | 6 Mac Os X, Virtual Customer Access System, Openssh and 3 more | 2022-12-13 | 4.6 MEDIUM | 8.1 HIGH |
| The (1) roaming_read and (2) roaming_write functions in roaming_common.c in the client in OpenSSH 5.x, 6.x, and 7.x before 7.1p2, when certain proxy and forward options are enabled, do not properly maintain connection file descriptors, which allows remote servers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact by requesting many forwardings. | |||||
| CVE-2016-10012 | 1 Openbsd | 1 Openssh | 2022-12-13 | 7.2 HIGH | 7.8 HIGH |
| The shared memory manager (associated with pre-authentication compression) in sshd in OpenSSH before 7.4 does not ensure that a bounds check is enforced by all compilers, which might allows local users to gain privileges by leveraging access to a sandboxed privilege-separation process, related to the m_zback and m_zlib data structures. | |||||
| CVE-2000-0143 | 2 Openbsd, Ssh | 2 Openssh, Ssh | 2022-08-17 | 4.6 MEDIUM | N/A |
| The SSH protocol server sshd allows local users without shell access to redirect a TCP connection through a service that uses the standard system password database for authentication, such as POP or FTP. | |||||
| CVE-2021-36368 | 2 Debian, Openbsd | 2 Debian Linux, Openssh | 2022-07-01 | 2.6 LOW | 3.7 LOW |
| ** DISPUTED ** An issue was discovered in OpenSSH before 8.9. If a client is using public-key authentication with agent forwarding but without -oLogLevel=verbose, and an attacker has silently modified the server to support the None authentication option, then the user cannot determine whether FIDO authentication is going to confirm that the user wishes to connect to that server, or that the user wishes to allow that server to connect to a different server on the user's behalf. NOTE: the vendor's position is "this is not an authentication bypass, since nothing is being bypassed." | |||||
| CVE-2021-28041 | 4 Fedoraproject, Netapp, Openbsd and 1 more | 11 Fedora, Cloud Backup, Hci Compute Node and 8 more | 2022-05-20 | 4.6 MEDIUM | 7.1 HIGH |
| ssh-agent in OpenSSH before 8.5 has a double free that may be relevant in a few less-common scenarios, such as unconstrained agent-socket access on a legacy operating system, or the forwarding of an agent to an attacker-controlled host. | |||||
| CVE-2020-14145 | 2 Netapp, Openbsd | 10 Active Iq Unified Manager, Aff A700s, Aff A700s Firmware and 7 more | 2022-04-28 | 4.3 MEDIUM | 5.9 MEDIUM |
| The client side in OpenSSH 5.7 through 8.4 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). NOTE: some reports state that 8.5 and 8.6 are also affected. | |||||
| CVE-2016-20012 | 2 Netapp, Openbsd | 5 Clustered Data Ontap, Hci Management Node, Ontap Select Deploy Administration Utility and 2 more | 2022-04-18 | 4.3 MEDIUM | 5.3 MEDIUM |
| ** DISPUTED ** OpenSSH through 8.7 allows remote attackers, who have a suspicion that a certain combination of username and public key is known to an SSH server, to test whether this suspicion is correct. This occurs because a challenge is sent only when that combination could be valid for a login session. NOTE: the vendor does not recognize user enumeration as a vulnerability for this product. | |||||
| CVE-2016-10708 | 4 Canonical, Debian, Netapp and 1 more | 12 Ubuntu Linux, Debian Linux, Cloud Backup and 9 more | 2021-09-14 | 5.0 MEDIUM | 7.5 HIGH |
| sshd in OpenSSH before 7.4 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an out-of-sequence NEWKEYS message, as demonstrated by Honggfuzz, related to kex.c and packet.c. | |||||
| CVE-2007-2768 | 2 Netapp, Openbsd | 5 Hci Management Node, Hci Storage Node, Solidfire and 2 more | 2021-04-01 | 4.3 MEDIUM | N/A |
| OpenSSH, when using OPIE (One-Time Passwords in Everything) for PAM, allows remote attackers to determine the existence of certain user accounts, which displays a different response if the user account exists and is configured to use one-time passwords (OTP), a similar issue to CVE-2007-2243. | |||||
| CVE-2020-12062 | 1 Openbsd | 1 Openssh | 2020-06-04 | 5.0 MEDIUM | 7.5 HIGH |
| ** DISPUTED ** The scp client in OpenSSH 8.2 incorrectly sends duplicate responses to the server upon a utimes system call failure, which allows a malicious unprivileged user on the remote server to overwrite arbitrary files in the client's download directory by creating a crafted subdirectory anywhere on the remote server. The victim must use the command scp -rp to download a file hierarchy containing, anywhere inside, this crafted subdirectory. NOTE: the vendor points out that "this attack can achieve no more than a hostile peer is already able to achieve within the scp protocol" and "utimes does not fail under normal circumstances." | |||||
| CVE-2013-4548 | 1 Openbsd | 1 Openssh | 2019-10-09 | 6.0 MEDIUM | N/A |
| The mm_newkeys_from_blob function in monitor_wrap.c in sshd in OpenSSH 6.2 and 6.3, when an AES-GCM cipher is used, does not properly initialize memory for a MAC context data structure, which allows remote authenticated users to bypass intended ForceCommand and login-shell restrictions via packet data that provides a crafted callback address. | |||||
| CVE-2018-15919 | 2 Netapp, Openbsd | 7 Cloud Backup, Cn1610, Cn1610 Firmware and 4 more | 2019-03-07 | 5.0 MEDIUM | 5.3 MEDIUM |
| Remotely observable behaviour in auth-gss2.c in OpenSSH through 7.8 could be used by remote attackers to detect existence of users on a target system when GSS2 is in use. NOTE: the discoverer states 'We understand that the OpenSSH developers do not want to treat such a username enumeration (or "oracle") as a vulnerability.' | |||||
