CVSS: 7.5EPSS: 0%CPEs: 5EXPL: 0CVE-2023-6476 – Cri-o: pods are able to break out of resource confinement on cgroupv2
https://notcve.org/view.php?id=CVE-2023-6476
A flaw was found in CRI-O that involves an experimental annotation leading to a container being unconfined. This may allow a pod to specify and get any amount of memory/cpu, circumventing the kubernetes scheduler and potentially resulting in a denial of service in the node. Se encontró una falla en CRI-O que involucra una anotación experimental que lleva a que un contenedor no esté confinado. Esto puede permitir que un pod especifique y obtenga cualquier cantidad de memoria/CPU, eludiendo el programador de Kubernetes y potencialmente provocando una denegación de servicio en el nodo. • https://access.redhat.com/errata/RHSA-2024:0195 https://access.redhat.com/errata/RHSA-2024:0207 https://access.redhat.com/security/cve/CVE-2023-6476 https://bugzilla.redhat.com/show_bug.cgi?id=2253994 • CWE-770: Allocation of Resources Without Limits or Throttling •

https://notcve.org/view.php?id=CVE-2022-3466
The version of cri-o as released for Red Hat OpenShift Container Platform 4.9.48, 4.10.31, and 4.11.6 via RHBA-2022:6316, RHBA-2022:6257, and RHBA-2022:6658, respectively, included an incorrect version of cri-o missing the fix for CVE-2022-27652, which was previously fixed in OCP 4.9.41 and 4.10.12 via RHBA-2022:5433 and RHSA-2022:1600. This issue could allow an attacker with access to programs with inheritable file capabilities to elevate those capabilities to the permitted set when execve(2) runs.

CVSS: 7.5EPSS: 0%CPEs: 41EXPL: 0CVE-2021-3695 – grub2: Crafted PNG grayscale images may lead to out-of-bounds write in heap
https://notcve.org/view.php?id=CVE-2021-3695
A crafted 16-bit grayscale PNG image may lead to a out-of-bounds write in the heap area. An attacker may take advantage of that to cause heap data corruption or eventually arbitrary code execution and circumvent secure boot protections. This issue has a high complexity to be exploited as an attacker needs to perform some triage over the heap layout to achieve signifcant results, also the values written into the memory are repeated three times in a row making difficult to produce valid payloads. This flaw affects grub2 versions prior grub-2.12. Una imagen PNG en escala de grises de 16 bits diseñada puede conllevar a una escritura fuera de límites en el área de la pila. • https://bugzilla.redhat.com/show_bug.cgi?id=1991685 https://security.gentoo.org/glsa/202209-12 https://security.netapp.com/advisory/ntap-20220930-0001 https://access.redhat.com/security/cve/CVE-2021-3695 • CWE-787: Out-of-bounds Write •
CVSS: 6.9EPSS: 0%CPEs: 40EXPL: 0CVE-2021-3696 – grub2: Crafted PNG image may lead to out-of-bound write during huffman table handling
https://notcve.org/view.php?id=CVE-2021-3696
A heap out-of-bounds write may heppen during the handling of Huffman tables in the PNG reader. This may lead to data corruption in the heap space. Confidentiality, Integrity and Availablity impact may be considered Low as it's very complex to an attacker control the encoding and positioning of corrupted Huffman entries to achieve results such as arbitrary code execution and/or secure boot circumvention. This flaw affects grub2 versions prior grub-2.12.

https://notcve.org/view.php?id=CVE-2021-3697
A crafted JPEG image may lead the JPEG reader to underflow its data pointer, allowing user-controlled data to be written in heap. To a successful to be performed the attacker needs to perform some triage over the heap layout and craft an image with a malicious format and payload. This vulnerability can lead to data corruption and eventual code execution or secure boot circumvention. This flaw affects grub2 versions prior grub-2.12. Una imagen JPEG diseñada puede conllevar que el lector de JPEG desborde su puntero de datos, permitiendo que los datos controlados por el usuario sean escritos en la pila. • https://bugzilla.redhat.com/show_bug.cgi?id=1991687 https://security.gentoo.org/glsa/202209-12 https://security.netapp.com/advisory/ntap-20220930-0001 https://access.redhat.com/security/cve/CVE-2021-3697 • CWE-787: Out-of-bounds Write •
