Astra Linux – Vulnerability in Erlang, Paramiko

The SSH transport protocol, with certain OpenSSH extensions, found in OpenSSH versions prior to 9.6 and other products, allows remote attackers to bypass integrity checks. As a result, some packets may be omitted from the extension negotiation message. Consequently, the client and server may end ...

Ubuntu 16.04 ESM / 18.04 ESM : OpenSSH vulnerabilities (USN-6560-2)

The remote Ubuntu 16.04 ESM / 18.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6560-2 advisory. USN-6560-1 fixed several vulnerabilities in OpenSSH. This update provides the corresponding update for Ubuntu 16.04 LTS and Ubuntu 18.04 LTS...

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 [email protected] and (if CBC is used) the [email protected] MAC algorithms. This also affects Maverick Synergy Java SSH API before 3.1.0-SNAPSHOT Dropbear through 2022.83 Ssh before 5.1.1 in Erlang/OTP PuTTY before 0.80 AsyncSSH before 2.14.2 golang.org/x/crypto before 0.17.0 libssh before 0.10.6 libssh2

Summary Terrapin is a prefix truncation attack targeting the SSH protocol. More precisely, Terrapin breaks the integrity of SSH's secure channel. By carefully adjusting the sequence numbers during the handshake, an attacker can remove an arbitrary amount of messages sent by the client or server a...
