https://notcve.org/view.php?id=CVE-2023-5090
A flaw was found in KVM. An improper check in svm_set_x2apic_msr_interception() may allow direct access to host x2apic msrs when the guest resets its apic, potentially leading to a denial of service condition. Se encontró una falla en KVM. Una verificación incorrecta en svm_set_x2apic_msr_interception() puede permitir el acceso directo al host x2apic msrs cuando el invitado restablece su apic, lo que podría provocar una condición de denegación de servicio. • https://access.redhat.com/errata/RHSA-2024:3854 https://access.redhat.com/errata/RHSA-2024:3855 https://access.redhat.com/errata/RHSA-2024:4211 https://access.redhat.com/errata/RHSA-2024:4352 https://access.redhat.com/security/cve/CVE-2023-5090 https://bugzilla.redhat.com/show_bug.cgi?id=2248122 https://access.redhat.com/errata/RHSA-2024:2758 • CWE-755: Improper Handling of Exceptional Conditions •

https://notcve.org/view.php?id=CVE-2023-5824
Squid is vulnerable to Denial of Service attack against HTTP and HTTPS clients due to an Improper Handling of Structural Elements bug. Squid es vulnerable a ataques de Denegación de Servicio contra clientes HTTP y HTTPS debido a un error en el manejo inadecuado de elementos estructurales. A flaw was found in Squid. The limits applied for validation of HTTP response headers are applied before caching. However, Squid may grow a cached HTTP response header beyond the configured maximum size, causing a stall or crash of the worker process when a large header is retrieved from the disk cache, resulting in a denial of service. • https://access.redhat.com/errata/RHSA-2023:7465 https://access.redhat.com/errata/RHSA-2023:7668 https://access.redhat.com/errata/RHSA-2024:0072 https://access.redhat.com/errata/RHSA-2024:0397 https://access.redhat.com/errata/RHSA-2024:0771 https://access.redhat.com/errata/RHSA-2024:0772 https://access.redhat.com/errata/RHSA-2024:0773 https://access.redhat.com/errata/RHSA-2024:1153 https://access.redhat.com/security/cve/CVE-2023-5824 https://bugzilla.redhat.com/show • CWE-755: Improper Handling of Exceptional Conditions •

https://notcve.org/view.php?id=CVE-2023-5178
A use-after-free vulnerability was found in drivers/nvme/target/tcp.c` in `nvmet_tcp_free_crypto` due to a logical bug in the NVMe/TCP subsystem in the Linux kernel. This issue may allow a malicious user to cause a use-after-free and double-free problem, which may permit remote code execution or lead to local privilege escalation. Se encontró una vulnerabilidad de use-after-free en drivers/nvme/target/tcp.c` en `nvmet_tcp_free_crypto` debido a un error lógico en el subsistema NVMe-oF/TCP en el kernel de Linux. Este problema puede permitir que un usuario malintencionado cause un problema de use-after-free y double-free, lo que puede permitir la ejecución remota de código o provocar una escalada de privilegios locales en caso de que el atacante ya tenga privilegios locales. • https://github.com/rockrid3r/CVE-2023-5178 https://access.redhat.com/errata/RHSA-2023:7370 https://access.redhat.com/errata/RHSA-2023:7379 https://access.redhat.com/errata/RHSA-2023:7418 https://access.redhat.com/errata/RHSA-2023:7548 https://access.redhat.com/errata/RHSA-2023:7549 https://access.redhat.com/errata/RHSA-2023:7551 https://access.redhat.com/errata/RHSA-2023:7554 https://access.redhat.com/errata/RHSA-2023:7557 https://access.redhat.com/errata/RHSA-2023 • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2023-5633
The reference count changes made as part of the CVE-2023-33951 and CVE-2023-33952 fixes exposed a use-after-free flaw in the way memory objects were handled when they were being used to store a surface. When running inside a VMware guest with 3D acceleration enabled, a local, unprivileged user could potentially use this flaw to escalate their privileges. Los cambios en el recuento de referencias realizados como parte de las correcciones CVE-2023-33951 y CVE-2023-33952 expusieron una falla de use-after-free en la forma en que se manejaban los objetos de memoria cuando se usaban para almacenar una superficie. Cuando se ejecuta dentro de un invitado de VMware con la aceleración 3D habilitada, un usuario local sin privilegios podría utilizar esta falla para aumentar sus privilegios. • https://access.redhat.com/errata/RHSA-2024:0113 https://access.redhat.com/errata/RHSA-2024:0134 https://access.redhat.com/errata/RHSA-2024:0461 https://access.redhat.com/errata/RHSA-2024:1404 https://access.redhat.com/errata/RHSA-2024:4823 https://access.redhat.com/errata/RHSA-2024:4831 https://access.redhat.com/security/cve/CVE-2023-5633 https://bugzilla.redhat.com/show_bug.cgi?id=2245663 • CWE-416: Use After Free •
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 •
