CVSS: 6.5EPSS: 0%CPEs: 27EXPL: 1CVE-2021-3733 – python: urllib: Regular expression DoS in AbstractBasicAuthHandler
https://notcve.org/view.php?id=CVE-2021-3733
There's a flaw in urllib's AbstractBasicAuthHandler class. An attacker who controls a malicious HTTP server that an HTTP client (such as web browser) connects to, could trigger a Regular Expression Denial of Service (ReDOS) during an authentication request with a specially crafted payload that is sent by the server to the client. The greatest threat that this flaw poses is to application availability. Se presenta un fallo en la clase AbstractBasicAuthHandler de urllib. Un atacante que controle un servidor HTTP malicioso al que se conecte un cliente HTTP (como un navegador web), podría desencadenar una Denegación de Servicio por Expresión Regular (ReDOS) durante una petición de autenticación con una carga útil especialmente diseñada que sea enviada por el servidor al cliente. • https://bugs.python.org/issue43075 https://bugzilla.redhat.com/show_bug.cgi?id=1995234 https://github.com/python/cpython/commit/7215d1ae25525c92b026166f9d5cac85fb https://github.com/python/cpython/pull/24391 https://lists.debian.org/debian-lts-announce/2023/05/msg00024.html https://lists.debian.org/debian-lts-announce/2023/06/msg00039.html https://security.netapp.com/advisory/ntap-20220407-0001 https://ubuntu.com/security/CVE-2021-3733 https://access.redhat.com/security/cve/CVE-2021-3733 • CWE-400: Uncontrolled Resource Consumption •
CVSS: 8.8EPSS: 0%CPEs: 76EXPL: 1CVE-2021-3656 – kernel: SVM nested virtualization issue in KVM (VMLOAD/VMSAVE)
https://notcve.org/view.php?id=CVE-2021-3656
A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested guest (L2). Due to improper validation of the "virt_ext" field, this issue could allow a malicious L1 to disable both VMLOAD/VMSAVE intercepts and VLS (Virtual VMLOAD/VMSAVE) for the L2 guest. As a result, the L2 guest would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak of sensitive data or potential guest-to-host escape. Se ha encontrado un fallo en el código AMD de KVM para soportar la virtualización anidada SVM. • https://github.com/rami08448/CVE-2021-3656-Demo https://bugzilla.redhat.com/show_bug.cgi?id=1983988 https://git.kernel.org/pub/scm/virt/kvm/kvm.git/commit/?id=c7dfa4009965a9b2d7b329ee970eb8da0d32f0bc https://github.com/torvalds/linux/commit/c7dfa4009965a9b2d7b329ee970eb8da0d32f0bc https://www.openwall.com/lists/oss-security/2021/08/16/1 https://access.redhat.com/security/cve/CVE-2021-3656 • CWE-862: Missing Authorization •
