CVSS: 5.9EPSS: 96%CPEs: 79EXPL: 1CVE-2023-48795 – ssh: Prefix truncation attack on Binary Packet Protocol (BPP)
https://notcve.org/view.php?id=CVE-2023-48795
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 chacha20-poly1305@openssh.com and (if CBC is used) the -etm@openssh.com MAC algorithms.

A flaw was found in xorg-server. Querying or changing XKB button actions such as moving from a touchpad to a mouse can result in out-of-bounds memory reads and writes. This may allow local privilege escalation or possible remote code execution in cases where X11 forwarding is involved. Se encontró una falla en xorg-server.

Bluetooth HID Hosts in BlueZ may permit an unauthenticated Peripheral role HID Device to initiate and establish an encrypted connection, and accept HID keyboard reports, potentially permitting injection of HID messages when no user interaction has occurred in the Central role to authorize such access. An example affected package is bluez 5.64-0ubuntu1 in Ubuntu 22.04LTS. NOTE: in some cases, a CVE-2020-0556 mitigation would have already addressed this Bluetooth HID Hosts issue. Bluetooth HID Hosts in BlueZ pueden permitir que un dispositivo HID con función periférica no autenticada inicie y establezca una conexión cifrada y acepte informes de teclado HID, lo que potencialmente permite la inyección de mensajes HID cuando no se ha producido ninguna interacción del usuario en la función central para autorizar dicho acceso. Un ejemplo de paquete afectado es bluez 5.64-0ubuntu1 en Ubuntu 22.04LTS. • http://changelogs.ubuntu.com/changelogs/pool/main/b/bluez/bluez_5.64-0ubuntu1/changelog http://seclists.org/fulldisclosure/2023/Dec/7 http://seclists.org/fulldisclosure/2023/Dec/9 https://bluetooth.com https://git.kernel.org/pub/scm/bluetooth/bluez.git/commit/profiles/input?id=25a471a83e02e1effb15d5a488b3f0085eaeb675 https://github.com/skysafe/reblog/tree/main/cve-2023-45866 https://lists.debian.org/debian-lts-announce/2023/12/msg00011.html https://lists.fedoraproject.org/archives/list/package • CWE-287: Improper Authentication •

The ACEManager component of ALEOS 4.16 and earlier does not perform input sanitization during authentication, which could potentially result in a Denial of Service (DoS) condition for ACEManager without impairing other router functions. ACEManager recovers from the DoS condition by restarting within ten seconds of becoming unavailable.
