CVSS: 7.4EPSS: 0%CPEs: 10EXPL: 0CVE-2023-5380 – Xorg-x11-server: use-after-free bug in destroywindow
https://notcve.org/view.php?id=CVE-2023-5380
A use-after-free flaw was found in the xorg-x11-server. An X server crash may occur in a very specific and legacy configuration (a multi-screen setup with multiple protocol screens, also known as Zaphod mode) if the pointer is warped from within a window on one screen to the root window of the other screen and if the original window is destroyed followed by another window being destroyed. Se encontró una falla de use-after-free en el servidor xorg-x11. Puede ocurrir una falla del servidor X en una configuración muy específica y heredada (una configuración de múltiples pantallas con múltiples pantallas de protocolo, también conocida como modo Zaphod) si el puntero se deforma desde dentro de una ventana en una pantalla a la ventana raíz de la otra pantalla y si la ventana original se destruye y luego se destruye otra ventana. This vulnerability allows local attackers to escalate privileges on affected installations of X.Org Server. • https://access.redhat.com/errata/RHSA-2023:7428 https://access.redhat.com/errata/RHSA-2024:2169 https://access.redhat.com/errata/RHSA-2024:2298 https://access.redhat.com/errata/RHSA-2024:2995 https://access.redhat.com/errata/RHSA-2024:3067 https://access.redhat.com/security/cve/CVE-2023-5380 https://bugzilla.redhat.com/show_bug.cgi?id=2244736 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/2WS5E7H4A5J3U5YBCTMRPQVGWK5LVH7D https://lists.fedoraprojec • CWE-416: Use After Free •
CVSS: 7.8EPSS: 0%CPEs: 17EXPL: 0CVE-2023-5367 – Xorg-x11-server: out-of-bounds write in xichangedeviceproperty/rrchangeoutputproperty
https://notcve.org/view.php?id=CVE-2023-5367
A out-of-bounds write flaw was found in the xorg-x11-server. This issue occurs due to an incorrect calculation of a buffer offset when copying data stored in the heap in the XIChangeDeviceProperty function in Xi/xiproperty.c and in RRChangeOutputProperty function in randr/rrproperty.c, allowing for possible escalation of privileges or denial of service. Se encontró una falla de escritura fuera de los límites en el servidor xorg-x11. Este problema ocurre debido a un cálculo incorrecto de un desplazamiento del búfer al copiar datos almacenados en el montón en la función XIChangeDeviceProperty en Xi/xiproperty.c y en la función RRChangeOutputProperty en randr/rrproperty.c, lo que permite una posible escalada de privilegios o Denegación de Servicio (DoS). . This vulnerability allows local attackers to escalate privileges on affected installations of X.Org Server. • https://access.redhat.com/errata/RHSA-2023:6802 https://access.redhat.com/errata/RHSA-2023:6808 https://access.redhat.com/errata/RHSA-2023:7373 https://access.redhat.com/errata/RHSA-2023:7388 https://access.redhat.com/errata/RHSA-2023:7405 https://access.redhat.com/errata/RHSA-2023:7428 https://access.redhat.com/errata/RHSA-2023:7436 https://access.redhat.com/errata/RHSA-2023:7526 https://access.redhat.com/errata/RHSA-2023:7533 https://access.redhat.com/errata/RHSA • CWE-787: Out-of-bounds Write •
CVSS: 7.5EPSS: 83%CPEs: 444EXPL: 7CVE-2023-44487 – HTTP/2 Rapid Reset Attack Vulnerability
https://notcve.org/view.php?id=CVE-2023-44487
The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023. El protocolo HTTP/2 permite una denegación de servicio (consumo de recursos del servidor) porque la cancelación de solicitudes puede restablecer muchas transmisiones rápidamente, como se explotó en la naturaleza entre agosto y octubre de 2023. A flaw was found in handling multiplexed streams in the HTTP/2 protocol. A client can repeatedly make a request for a new multiplex stream and immediately send an RST_STREAM frame to cancel it. This creates extra work for the server setting up and tearing down the streams while not hitting any server-side limit for the maximum number of active streams per connection, resulting in a denial of service due to server resource consumption. • https://github.com/imabee101/CVE-2023-44487 https://github.com/studiogangster/CVE-2023-44487 https://github.com/bcdannyboy/CVE-2023-44487 https://github.com/sigridou/CVE-2023-44487- https://github.com/ByteHackr/CVE-2023-44487 https://github.com/ReToCode/golang-CVE-2023-44487 http://www.openwall.com/lists/oss-security/2023/10/13/4 http://www.openwall.com/lists/oss-security/2023/10/13/9 http://www.openwall.com/lists/oss-security/2023/10/18/4 http://www. • CWE-400: Uncontrolled Resource Consumption •
CVSS: 7.8EPSS: 0%CPEs: 5EXPL: 2CVE-2023-42753 – Kernel: netfilter: potential slab-out-of-bound access due to integer underflow
https://notcve.org/view.php?id=CVE-2023-42753
An array indexing vulnerability was found in the netfilter subsystem of the Linux kernel. A missing macro could lead to a miscalculation of the `h->nets` array offset, providing attackers with the primitive to arbitrarily increment/decrement a memory buffer out-of-bound. This issue may allow a local user to crash the system or potentially escalate their privileges on the system. Se encontró una vulnerabilidad de indexación de matrices en el subsistema netfilter del kernel de Linux. Una macro faltante podría provocar un error de cálculo del desplazamiento de la matriz `h->nets`, proporcionando a los atacantes la primitiva de incrementar/disminuir arbitrariamente un búfer de memoria fuera de límites. • http://packetstormsecurity.com/files/175963/Kernel-Live-Patch-Security-Notice-LSN-0099-1.html https://access.redhat.com/errata/RHSA-2023:7370 https://access.redhat.com/errata/RHSA-2023:7379 https://access.redhat.com/errata/RHSA-2023:7382 https://access.redhat.com/errata/RHSA-2023:7389 https://access.redhat.com/errata/RHSA-2023:7411 https://access.redhat.com/errata/RHSA-2023:7418 https://access.redhat.com/errata/RHSA-2023:7539 https://access.redhat.com/errata/RHSA-2023:7558 h • CWE-787: Out-of-bounds Write •

Information exposure through microarchitectural state after transient execution in certain vector execution units for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. La exposición de información a través del estado microarquitectónico tras la ejecución transitoria en determinadas unidades de ejecución vectorial de algunos procesadores Intel(R) puede permitir a un usuario autenticado la divulgación potencial de información a través del acceso local. A Gather Data Sampling (GDS) transient execution side-channel vulnerability was found affecting certain Intel processors. This issue may allow a local attacker using gather instruction (load from memory) to infer stale data from previously used vector registers on the same physical core. • http://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00828.html https://access.redhat.com/solutions/7027704 https://aws.amazon.com/security/security-bulletins/AWS-2023-007 https://downfall.page https://lists.debian.org/debian-lts-announce/2023/08/msg00013.html https://lists.debian.org/debian-lts-announce/2023/08/msg00026.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/HKKYIK2EASDNUV4I7EFJKNBVO3KCKGRR https://lists.fedoraproject.org • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-203: Observable Discrepancy CWE-1342: Information Exposure through Microarchitectural State after Transient Execution •
