| CVE-2016-7406 | Cri | 0.65 | 9.8 | 0.10 | Mar 3, 2017 | Format string vulnerability in Dropbear SSH before 2016.74 allows remote attackers to execute arbitrary code via format string specifiers in the (1) username or (2) host argument. | ||
| CVE-2016-7407 | Cri | 0.64 | 9.8 | 0.06 | Mar 3, 2017 | The dropbearconvert command in Dropbear SSH before 2016.74 allows attackers to execute arbitrary code via a crafted OpenSSH key file. | ||
| CVE-2017-9078 | Hig | 0.58 | 8.8 | 0.05 | May 19, 2017 | 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-2016-7408 | Hig | 0.58 | 8.8 | 0.04 | Mar 3, 2017 | The dbclient in Dropbear SSH before 2016.74 allows remote attackers to execute arbitrary code via a crafted (1) -m or (2) -c argument. | ||
| CVE-2016-3116 | Med | 0.46 | 6.4 | 0.19 | Mar 22, 2016 | CRLF injection vulnerability in Dropbear SSH before 2016.72 allows remote authenticated users to bypass intended shell-command restrictions via crafted X11 forwarding data. | ||
| CVE-2023-48795 | Med | 0.39 | 5.9 | 0.93 | Dec 18, 2023 | 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… | ||
| CVE-2016-7409 | Med | 0.36 | 5.5 | 0.00 | Mar 3, 2017 | The dbclient and server in Dropbear SSH before 2016.74, when compiled with DEBUG_TRACE, allows local users to read process memory via the -v argument, related to a failed remote ident. | ||
