CVE-2023-39198 – Kernel: qxl: race condition leading to use-after-free in qxl_mode_dumb_create()
https://notcve.org/view.php?id=CVE-2023-39198
A race condition was found in the QXL driver in the Linux kernel. The qxl_mode_dumb_create() function dereferences the qobj returned by the qxl_gem_object_create_with_handle(), but the handle is the only one holding a reference to it. This flaw allows an attacker to guess the returned handle value and trigger a use-after-free issue, potentially leading to a denial of service or privilege escalation. Se encontró una condición de ejecución en el controlador QXL del kernel de Linux. La función qxl_mode_dumb_create() desreferencia el qobj devuelto por qxl_gem_object_create_with_handle(), pero el identificador es el único que contiene una referencia a él. • https://access.redhat.com/errata/RHSA-2024:2394 https://access.redhat.com/errata/RHSA-2024:2950 https://access.redhat.com/errata/RHSA-2024:3138 https://access.redhat.com/security/cve/CVE-2023-39198 https://bugzilla.redhat.com/show_bug.cgi?id=2218332 https://lists.debian.org/debian-lts-announce/2024/06/msg00016.html • CWE-416: Use After Free •
CVE-2023-4535 – Opensc: out-of-bounds read in myeid driver handling encryption using symmetric keys
https://notcve.org/view.php?id=CVE-2023-4535
An out-of-bounds read vulnerability was found in OpenSC packages within the MyEID driver when handling symmetric key encryption. Exploiting this flaw requires an attacker to have physical access to the computer and a specially crafted USB device or smart card. This flaw allows the attacker to manipulate APDU responses and potentially gain unauthorized access to sensitive data, compromising the system's security. Se encontró una vulnerabilidad de lectura fuera de los límites en los paquetes OpenSC dentro del controlador MyEID al manejar el cifrado de clave simétrica. Explotar esta falla requiere que un atacante tenga acceso físico a la computadora y a un dispositivo USB o tarjeta inteligente especialmente manipulado. • https://access.redhat.com/errata/RHSA-2023:7879 https://access.redhat.com/security/cve/CVE-2023-4535 https://bugzilla.redhat.com/show_bug.cgi?id=2240914 https://github.com/OpenSC/OpenSC/commit/f1993dc4e0b33050b8f72a3558ee88b24c4063b2 https://github.com/OpenSC/OpenSC/issues/2792#issuecomment-1674806651 https://github.com/OpenSC/OpenSC/releases/tag/0.24.0-rc1 https://github.com/OpenSC/OpenSC/wiki/OpenSC-security-advisories https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject • CWE-125: Out-of-bounds Read •
CVE-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 •
CVE-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 •
