| CVE-2021-36369 | 2 Debian, Dropbear Ssh Project | 2 Debian Linux, Dropbear Ssh | 2023-01-20 | N/A | 7.5 HIGH |
| An issue was discovered in Dropbear through 2020.81. Due to a non-RFC-compliant check of the available authentication methods in the client-side SSH code, it is possible for an SSH server to change the login process in its favor. This attack can bypass additional security measures such as FIDO2 tokens or SSH-Askpass. Thus, it allows an attacker to abuse a forwarded agent for logging on to another server unnoticed. | |||||
| CVE-2017-9078 | 3 Debian, Dropbear Ssh Project, Netapp | 4 Debian Linux, Dropbear Ssh, H410c and 1 more | 2022-07-11 | 8.5 HIGH | 8.8 HIGH |
| The server in Dropbear before 2017.75 might allow post-authentication root remote code execution because of a double free in cleanup of TCP listeners when the -a option is enabled. | |||||

| CVE-2019-12953 | 1 Dropbear Ssh Project | 1 Dropbear Ssh | 2021-07-21 | 5.0 MEDIUM | 5.3 MEDIUM |
| Dropbear 2011.54 through 2018.76 has an inconsistent failure delay that may lead to revealing valid usernames, a different issue than CVE-2018-15599. | |||||
| CVE-2018-15599 | 2 Debian, Dropbear Ssh Project | 2 Debian Linux, Dropbear Ssh | 2020-12-30 | 5.0 MEDIUM | 5.3 MEDIUM |
| The recv_msg_userauth_request function in svr-auth.c in Dropbear through 2018.76 is prone to a user enumeration vulnerability because username validity affects how fields in SSH_MSG_USERAUTH messages are handled, a similar issue to CVE-2018-15473 in an unrelated codebase. | |||||
| CVE-2017-2659 | 1 Dropbear Ssh Project | 1 Dropbear Ssh | 2019-10-09 | 5.0 MEDIUM | 7.5 HIGH |
| It was found that dropbear before version 2013.59 with GSSAPI leaks whether given username is valid or invalid. When an invalid username is given, the GSSAPI authentication failure was incorrectly counted towards the maximum allowed number of password attempts. | |||||
| CVE-2017-9079 | 2 Debian, Dropbear Ssh Project | 2 Debian Linux, Dropbear Ssh | 2019-10-04 | 4.7 MEDIUM | 4.7 MEDIUM |
| Dropbear before 2017.75 might allow local users to read certain files as root, if the file has the authorized_keys file format with a command= option. This occurs because ~/.ssh/authorized_keys is read with root privileges and symlinks are followed. | |||||
| CVE-2004-2486 | 1 Dropbear Ssh Project | 1 Dropbear Ssh | 2018-10-30 | 7.5 HIGH | N/A |

| CVE-2013-4421 | 1 Dropbear Ssh Project | 1 Dropbear Ssh | 2018-10-30 | 5.0 MEDIUM | N/A |
| The buf_decompress function in packet.c in Dropbear SSH Server before 2013.59 allows remote attackers to cause a denial of service (memory consumption) via a compressed packet that has a large size when it is decompressed. | |||||
| CVE-2013-4434 | 1 Dropbear Ssh Project | 1 Dropbear Ssh | 2018-10-30 | 5.0 MEDIUM | N/A |
| Dropbear SSH Server before 2013.59 generates error messages for a failed logon attempt with different time delays depending on whether the user account exists, which allows remote attackers to discover valid usernames. | |||||
| CVE-2016-7408 | 1 Dropbear Ssh Project | 1 Dropbear Ssh | 2017-03-04 | 6.5 MEDIUM | 8.8 HIGH |
