CVE-2026-21901

CVE-2026-21901 describes a NULL pointer dereference in Juniper Networks Junos OS and Junos OS Evolved mgd (management daemon) when a local, high-privileged user configures or deactivates a specific 'system services ssh' parameter. The vulnerability causes an mgd crash and restart, enabling a sust...

SSH Configuration Injection

Coder is vulnerable to SSH Configuration Injection. The vulnerability is due to coder config-ssh writing server-supplied HostnameSuffix and SSHConfigOptions into the user's /.ssh/config without properly sanitizing embedded newlines or restricting SSH directives, which allows an attacker controlli...

Arbitrary Command Injection

Overview Affected versions of this package are vulnerable to Arbitrary Command Injection via the ssh process. An attacker can execute arbitrary commands on the operator's workstation by injecting malicious OpenSSH options when the operator runs non-interactive SSH commands. Remediation There is n...

CVE-2026-15171

A flaw was found in Wireshark's SSH Secure Shell protocol dissector. A remote attacker could craft a malicious network capture file that, when opened by a user, would cause the Wireshark application to crash. This vulnerability leads to a denial of service, preventing the user from analyzing...

CVE-2026-47831

Use of a cryptographically weak random number generator in the GenerateRandomPassword function in bosh-windows-stemcell-builder allows a remote attacker to brute-force the resulting SSH login via TCP/22. Affected versions: bosh-windows-stemcell-builder versions prior to v2019.98...

golang.org/x/crypto/ssh: golang.org/x/crypto/ssh: Denial of Service via resource leak from unsolicited SSH responses

A flaw was found in golang.org/x/crypto/ssh. A remote malicious SSH peer can exploit this by sending unsolicited global request responses, which fills an internal buffer and blocks the connection's read loop. This prevents the associated resources from being released, leading to a resource leak p...
