CVSS: 7.0EPSS: 0%CPEs: 4EXPL: 0CVE-2023-5088 – Qemu: improper ide controller reset can lead to mbr overwrite
https://notcve.org/view.php?id=CVE-2023-5088
A bug in QEMU could cause a guest I/O operation otherwise addressed to an arbitrary disk offset to be targeted to offset 0 instead (potentially overwriting the VM's boot code). This could be used, for example, by L2 guests with a virtual disk (vdiskL2) stored on a virtual disk of an L1 (vdiskL1) hypervisor to read and/or write data to LBA 0 of vdiskL1, potentially gaining control of L1 at its next reboot. Un error en QEMU podría causar que una operación de E/S de invitado que de otro modo estaría dirigida a un desplazamiento de disco arbitrario se dirija al desplazamiento 0 (potencialmente sobrescribiendo el código de arranque de la VM). Esto podría ser utilizado, por ejemplo, por invitados L2 con un disco virtual (vdiskL2) almacenado en un disco virtual de un hipervisor L1 (vdiskL1) para leer y/o escribir datos en el LBA 0 de vdiskL1, obteniendo potencialmente el control de L1 en su próximo reinicio. • https://access.redhat.com/errata/RHSA-2024:2135 https://access.redhat.com/errata/RHSA-2024:2962 https://access.redhat.com/security/cve/CVE-2023-5088 https://bugzilla.redhat.com/show_bug.cgi?id=2247283 https://lists.debian.org/debian-lts-announce/2024/03/msg00012.html https://lore.kernel.org/all/20230921160712.99521-1-simon.rowe@nutanix.com/T https://security.netapp.com/advisory/ntap-20231208-0005 • CWE-662: Improper Synchronization CWE-821: Incorrect Synchronization •

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 •
