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 •

PVRIC (PowerVR Image Compression) on Imagination 2018 and later GPU devices offers software-transparent compression that enables cross-origin pixel-stealing attacks against feTurbulence and feBlend in the SVG Filter specification, aka a GPU.zip issue. For example, attackers can sometimes accurately determine text contained on a web page from one origin if they control a resource from a different origin. PVRIC (PowerVR Image Compression) en Imagination 2018 y dispositivos GPU posteriores ofrece compresión transparente por software que permite ataques de robo de píxeles de origen cruzado contra feTurbulence y feBlend en la especificación del filtro SVG, también conocido como un problema GPU.zip. Por ejemplo, los atacantes a veces pueden determinar con precisión el texto contenido en una página web de un origen si controlan un recurso de un origen diferente. • https://arstechnica.com/security/2023/09/gpus-from-all-major-suppliers-are-vulnerable-to-new-pixel-stealing-attack https://blog.imaginationtech.com/introducing-pvric4-taking-image-compression-to-the-next-level https://blog.imaginationtech.com/reducing-bandwidth-pvric https://github.com/UT-Security/gpu-zip https://news.ycombinator.com/item?id=37663159 https://www.bleepingcomputer.com/news/security/modern-gpus-vulnerable-to-new-gpuzip-side-channel-attack https://www.hertzbleed.com/gpu.zip https://www.her • CWE-203: Observable Discrepancy •
CVSS: 7.8EPSS: 0%CPEs: 8EXPL: 0CVE-2023-3777 – Use-after-free in Linux kernel's netfilter: nf_tables component
https://notcve.org/view.php?id=CVE-2023-3777
A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. When nf_tables_delrule() is flushing table rules, it is not checked whether the chain is bound and the chain's owner rule can also release the objects in certain circumstances. We recommend upgrading past commit 6eaf41e87a223ae6f8e7a28d6e78384ad7e407f8. Una vulnerabilidad de Use-After-Free en el componente netfilter: nf_tables del kernel de Linux puede explotarse para lograr una escalada de privilegios local. Cuando nf_tables_delrule() vacía las reglas de la tabla, no se verifica si la cadena está vinculada y la regla del propietario de la cadena también puede liberar los objetos en determinadas circunstancias. Recomendamos actualizar al pasado commit 6eaf41e87a223ae6f8e7a28d6e78384ad7e407f8. A use-after-free flaw was found in the Linux kernel's netfilter: nf_tables component, which can be exploited to achieve local privilege escalation. • http://packetstormsecurity.com/files/175072/Kernel-Live-Patch-Security-Notice-LSN-0098-1.html http://packetstormsecurity.com/files/175963/Kernel-Live-Patch-Security-Notice-LSN-0099-1.html https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=6eaf41e87a223ae6f8e7a28d6e78384ad7e407f8 https://kernel.dance/6eaf41e87a223ae6f8e7a28d6e78384ad7e407f8 https://www.debian.org/security/2023/dsa-5492 https://access.redhat.com/security/cve/CVE-2023-3777 https://bugzilla.redhat.com/show_bug.cgi?id=223 • CWE-416: Use After Free •
