CVSS: 8.1EPSS: 0%CPEs: 54EXPL: 44CVE-2024-6387 – Openssh: regresshion - race condition in ssh allows rce/dos
https://notcve.org/view.php?id=CVE-2024-6387
A security regression (CVE-2006-5051) was discovered in OpenSSH's server (sshd). There is a race condition which can lead sshd to handle some signals in an unsafe manner. An unauthenticated, remote attacker may be able to trigger it by failing to authenticate within a set time period. Se encontró una condición de ejecución del controlador de señales en el servidor de OpenSSH (sshd), donde un cliente no se autentica dentro de los segundos de LoginGraceTime (120 de forma predeterminada, 600 en versiones anteriores de OpenSSH), luego se llama al controlador SIGALRM de sshd de forma asincrónica. Sin embargo, este controlador de señales llama a varias funciones que no son seguras para señales asíncronas, por ejemplo, syslog(). • https://github.com/l0n3m4n/CVE-2024-6387 https://github.com/thegenetic/CVE-2024-6387-exploit https://github.com/d0rb/CVE-2024-6387 https://github.com/devarshishimpi/CVE-2024-6387-Check https://github.com/AiGptCode/ssh_exploiter_CVE-2024-6387 https://github.com/Symbolexe/CVE-2024-6387 https://github.com/xonoxitron/regreSSHion https://github.com/PrincipalAnthony/CVE-2024-6387-Updated-x64bit https://github.com/4lxprime/regreSSHive https://github.com/shamo0/CVE-2024-6387_PoC https:&# • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-364: Signal Handler Race Condition •

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 •

CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 7CVE-2023-2640 – Canonical Ubuntu OverlayFS File System Missing Authorization Local Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2023-2640
On Ubuntu kernels carrying both c914c0e27eb0 and "UBUNTU: SAUCE: overlayfs: Skip permission checking for trusted.overlayfs.* xattrs", an unprivileged user may set privileged extended attributes on the mounted files, leading them to be set on the upper files without the appropriate security checks. This vulnerability allows local attackers to escalate privileges on affected installations of Canonical Ubuntu. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of attributes. The issue results from missing authorization before allowing access to functionality. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of root. • https://github.com/ThrynSec/CVE-2023-32629-CVE-2023-2640---POC-Escalation https://github.com/xS9NTX/CVE-2023-32629-CVE-2023-2640-Ubuntu-Privilege-Escalation-POC https://github.com/g1vi/CVE-2023-2640-CVE-2023-32629 https://github.com/Nkipohcs/CVE-2023-2640-CVE-2023-32629 https://github.com/musorblyat/CVE-2023-2640-CVE-2023-32629 https://github.com/K5LK/CVE-2023-2640-32629 https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-2640 https://lists.ubuntu.com/archives/ker • CWE-863: Incorrect Authorization •
