CVE-2026-73430

Russh (Rust SSH client/server library) before version 0.62.4 is affected. An unauthenticated SSH client can trigger a denial of service by sending SSH_MSG_KEX_ECDH_INIT with a 32-byte all-zero Q_C value. In Curve25519Kex::server_dh, the all-zero peer public value is accepted, leading to a zero sh...

CVE-2026-73429 Russh: client wrong-length X25519 `clone_from_slice` panic (pre-auth DoS)

Russh is a Rust SSH client & server library. Prior to 0.62.4, a malicious SSH server can crash a russh client session with a malformed KEXECDHREPLY containing a server ephemeral value that is not 32 bytes long. The client-side Curve25519Kex::computesharedsecret function in...

CVE-2026-5917

A flaw was found in libgit2 when built with the libssh2 SSH backend. This vulnerability allows a remote attacker to execute arbitrary commands on an SSH server. By crafting a malicious repository path containing unescaped shell metacharacters, an attacker can inject commands that are then...

CVE-2026-73281

A flaw was found in OpenSSH's ssh-agent component. A misinteraction between agent locking and the [email protected] extension allows operations intended for local execution to be performed remotely. This could enable a remote attacker to add PKCS11 tokens or utilize keys with destination...
