Russh is a Rust SSH client & server library. In versions 0.54.0 and below, the channel window adjust message of the SSH protocol is used to track the free space in the receive buffer of the other side of a channel. The current implementation takes the value from the message and adds it to an...

UBUNTU-CVE-2025-8114

A flaw was found in libssh, a library that implements the SSH protocol. When calculating the session ID during the key exchange KEX process, an allocation failure in cryptographic functions may lead to a NULL pointer dereference. This issue can cause the client or server to crash...

AZL-64794 CVE-2025-5987 affecting package libssh for versions less than 0.10.6-2

A flaw was found in libssh when using the ChaCha20 cipher with the OpenSSL library. If an attacker manages to exhaust the heap space, this error is not detected and may lead to libssh using a partially initialized cipher context. This occurs because the OpenSSL error code returned aliases with th...

golang.org/x/crypto/ssh: Denial of Service in the Key Exchange of golang.org/x/crypto/ssh

A flaw was found in the golang.org/x/crypto/ssh package. SSH clients and servers are vulnerable to increased resource consumption, possibly leading to memory exhaustion and a DoS. This can occur during key exchange when the other party is slow to respond during key exchange...

The vulnerability of the SSH protocol implementation in the Erlang/OTP library lies in the lack of authentication checks for a critical function, allowing attackers to execute arbitrary code.

The vulnerability of the SSH protocol implementation in the Erlang/OTP library set is related to the lack of authentication checks for a critical function. Exploiting this vulnerability allows an attacker operating remotely to execute arbitrary code by sending specially crafted SSH packets...

CVE-2024-45337

A flaw was found in the x/crypto/ssh go library. Applications and libraries that misuse the ServerConfig.PublicKeyCallback callback may be susceptible to an authorization bypass. For example, an attacker may send public keys A and B and authenticate with A. PublicKeyCallback would be called only...

CVE-2024-43410

CVE-2024-43410 (Russh) : The russh Rust SSH library is vulnerable to an OOM DoS caused by allocating memory based on an untrusted 4-byte packet length. An unauthenticated client can set this length to any value, triggering large allocations before authentication and potentially exhausting the ser...

CVE-2024-43410 Russh has an OOM Denial of Service due to allocation of untrusted amount

Russh is a Rust SSH client & server library. Allocating an untrusted amount of memory allows any unauthenticated user to OOM a russh server. An SSH packet consists of a 4-byte big-endian length, followed by a byte stream of this length. After parsing and potentially decrypting the 4-byte length,...
