CVE-2020-25660 – ceph: CEPHX_V2 replay attack protection lost
https://notcve.org/view.php?id=CVE-2020-25660
A flaw was found in the Cephx authentication protocol in versions before 15.2.6 and before 14.2.14, where it does not verify Ceph clients correctly and is then vulnerable to replay attacks in Nautilus. This flaw allows an attacker with access to the Ceph cluster network to authenticate with the Ceph service via a packet sniffer and perform actions allowed by the Ceph service. This issue is a reintroduction of CVE-2018-1128, affecting the msgr2 protocol. The msgr 2 protocol is used for all communication except older clients that do not support the msgr2 protocol. The msgr1 protocol is not affected. • https://bugzilla.redhat.com/show_bug.cgi?id=1890354 https://ceph.io/community/v15-2-6-octopus-released https://ceph.io/releases/v14-2-14-nautilus-released https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/UBC4KZ44QUQENTYZPVHORGL4K2KV5V4F https://security.gentoo.org/glsa/202105-39 https://access.redhat.com/security/cve/CVE-2020-25660 • CWE-294: Authentication Bypass by Capture-replay •
CVE-2020-14336 – openshift: restricted SCC allows pods to craft custom network packets
https://notcve.org/view.php?id=CVE-2020-14336
A flaw was found in the Restricted Security Context Constraints (SCC), where it allows pods to craft custom network packets. This flaw allows an attacker to cause a denial of service attack on an OpenShift Container Platform cluster if they can deploy pods. The highest threat from this vulnerability is to system availability. Se ha encontrado un fallo en las Restricciones de Contexto de Seguridad (SCC), que permite a los pods diseñar paquetes de red personalizados.

CVE-2020-15705 – GRUB2: avoid loading unsigned kernels when GRUB is booted directly under secureboot without shim
https://notcve.org/view.php?id=CVE-2020-15705
GRUB2 fails to validate kernel signature when booted directly without shim, allowing secure boot to be bypassed. This only affects systems where the kernel signing certificate has been imported directly into the secure boot database and the GRUB image is booted directly without the use of shim. This issue affects GRUB2 version 2.04 and prior versions. GRUB2 presenta un fallo al comprobar la firma del kernel cuando se inicia directamente sin cuña, permitiendo que el arranque seguro sea omitido. Esto solo afecta a los sistemas en los que el certificado de firma del kernel ha sido importado directamente a la base de datos de arranque seguro y la imagen de GRUB es iniciada directamente sin el uso de cuña. • http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00067.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00069.html http://ubuntu.com/security/notices/USN-4432-1 http://www.openwall.com/lists/oss-security/2020/07/29/3 http://www.openwall.com/lists/oss-security/2021/03/02/3 http://www.openwall.com/lists/oss-security/2021/09/17/2 http://www.openwall.com/lists/oss-security/2021/09/17/4 http://www.openwall.com/lists/oss-security • CWE-347: Improper Verification of Cryptographic Signature CWE-440: Expected Behavior Violation •
