2019-01-10 CVE-2018-20685 In OpenSSH 7.9, scp.c in the scp client allows remote SSH servers to bypass intended access restrictions via the filename of . or an empty filename. The impact is modifying the permissions of the target directory on the client side.

2018-08-17 CVE-2018-15473 OpenSSH through 7.7 is prone to a user enumeration vulnerability due to not delaying bailout for an invalid authenticating user until after the packet containing the request has been fully parsed, related to auth2-gss.c, auth2-hostbased.c, and auth2-pubkey.c. Ubuntu_linux, Debian_linux, Aff_baseboard_management_controller, Cloud_backup, Clustered_data_ontap, Cn1610_firmware, Data_ontap, Data_ontap_edge, Fas_baseboard_management_controller, Oncommand_unified_manager, Ontap_select_deploy, Service_processor, Steelstore_cloud_integrated_storage, Storage_replication_adapter, Vasa_provider, Virtual_storage_console, Openssh, Enterprise_linux_desktop, Enterprise_linux_server, Enterprise_linux_workstation 5.3
2017-10-26 CVE-2017-15906 The process_open function in sftp-server.c in OpenSSH before 7.6 does not properly prevent write operations in readonly mode, which allows attackers to create zero-length files. Openssh 5.3
2020-07-24 CVE-2020-15778 scp in OpenSSH through 8.3p1 allows command injection in scp.c remote function, as demonstrated by backtick characters in the destination argument. NOTE: the vendor reportedly has stated that they intentionally omit validation of "anomalous argument transfers" because that could "stand a great chance of breaking existing workflows." Openssh N/A
2020-06-29 CVE-2020-14145 The client side in OpenSSH 5.7 through 8.3 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). Openssh N/A
2020-06-01 CVE-2020-12062 ** 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... Openssh N/A
2014-01-29 CVE-2014-1692 The hash_buffer function in schnorr.c in OpenSSH through 6.4, when Makefile.inc is modified to enable the J-PAKE protocol, does not initialize certain data structures, which might allow remote attackers to cause a denial of service (memory corruption) or have unspecified other impact via vectors that trigger an error condition. Openssh N/A
2016-01-14 CVE-2016-0778 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. Mac_os_x, Virtual_customer_access_system, Openssh, Linux, Solaris, Unified_threat_management_software 8.1
2016-01-14 CVE-2016-0777 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. Mac_os_x, Remote_device_access_virtual_customer_access_system, Openssh, Linux, Solaris, Unified_threat_management_software 6.5
2007-05-21 CVE-2007-2768 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.
