| VCID-5kyz-5rns-2qfy | Matt Johnston Dropbear SSH server 0.47 and earlier, as used in embedded Linux devices and on general-purpose operating systems, allows remote attackers to cause a denial of service (connection slot exhaustion) via a large number of connection attempts that exceeds the MAX_UNAUTH_CLIENTS defined value of 30. |
CVE-2006-1206
|
| VCID-6ucx-wdc2-tuad | Multiple vulnerabilities have been found in Dropbear, the worst of which allows remote attackers to execute arbitrary code. |
CVE-2016-7406
|
| VCID-8apc-5c8s-k3ar | security update |
CVE-2017-9079
|
| VCID-9pmf-w3x7-5ugr | 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-2021-36369
|
| VCID-9vje-sxgj-9udj | dbclient in Dropbear SSH before 2025.88 allows command injection via an untrusted hostname argument, because a shell is used. |
CVE-2025-47203
|
| VCID-a1rw-pbvm-7kec | The DSS verification code in Dropbear SSH Server before 0.43 frees uninitialized variables, which might allow remote attackers to gain access. |
CVE-2004-2486
|
| VCID-a8c1-84ye-73en | Multiple vulnerabilities have been found in Dropbear, the worst of which allows remote attackers to execute arbitrary code. |
CVE-2016-7408
|
| VCID-adtn-2cnz-wfb9 | 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-2013-4421
|
| VCID-d17n-u3cw-cudj | 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-2017-2659
|
| VCID-d3s7-uqk1-47bq | security update |
CVE-2017-9078
|
| VCID-enpx-ej3b-n3gh | A flaw was found in Dropbear. When running in multi-user mode and authenticating users, the dropbear ssh server does the socket forwardings requested by the remote client as root, only switching to the logged-in user upon spawning a shell or performing some operations like reading the user's files. With the recent ability of also using unix domain sockets as the forwarding destination any user able to log in via ssh can connect to any unix socket with the root's credentials, bypassing both file system restrictions and any SO_PEERCRED / SO_PASSCRED checks performed by the peer. |
CVE-2025-14282
|
| VCID-fkyw-zr2t-y7dm | 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-2018-15599
|
| VCID-gdx4-w6cw-2kek | scp.c in Dropbear before 2020.79 mishandles the filename of . or an empty filename, a related issue to CVE-2018-20685. |
CVE-2020-36254
|
| VCID-guvt-ddvk-dbdk | dbclient in Dropbear SSH client before 0.49 does not sufficiently warn the user when it detects a hostkey mismatch, which might allow remote attackers to conduct man-in-the-middle attacks. |
CVE-2007-1099
|
| VCID-hmcm-aqkc-zfdm | 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-2019-12953
|
| VCID-jd36-dxz7-dfdy | Multiple vulnerabilities have been found in Dropbear, the worst of which could lead to arbitrary code execution. |
CVE-2012-0920
|
| VCID-jzn6-bzzf-nugp | Improper Validation of Integrity Check Value The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in chacha20-poly1305@openssh.com and (if CBC is used) the -etm@openssh.com MAC algorithms.
