https://notcve.org/view.php?id=CVE-2022-27191
The golang.org/x/crypto/ssh package before 0.0.0-20220314234659-1baeb1ce4c0b for Go allows an attacker to crash a server in certain circumstances involving AddHostKey. El paquete golang.org/x/crypto/ssh anterior a 0.0.0-20220314234659-1baeb1ce4c0b para Go permite a un atacante bloquear un servidor en ciertas circunstancias que implican AddHostKey A broken cryptographic algorithm flaw was found in golang.org/x/crypto/ssh. This issue causes a client to fail authentication with RSA keys to servers that reject signature algorithms based on SHA-2, enabling an attacker to crash the server, resulting in a loss of availability. • https://groups.google.com/g/golang-announce https://groups.google.com/g/golang-announce/c/-cp44ypCT5s https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DLUJZV3HBP56ADXU6QH2V7RNYUPMVBXQ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/EZ3S7LB65N54HXXBCB67P4TTOHTNPP5O https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HHGBEGJ54DZZGTXFUQNS7ZIG3E624YAF https://lists.fedoraproject.org/archives/list/package-announce%40lis • CWE-327: Use of a Broken or Risky Cryptographic Algorithm •
CVSS: 3.5EPSS: 0%CPEs: 1EXPL: 0CVE-2020-25688
https://notcve.org/view.php?id=CVE-2020-25688
A flaw was found in rhacm versions before 2.0.5 and before 2.1.0. Two internal service APIs were incorrectly provisioned using a test certificate from the source repository. This would result in all installations using the same certificates. If an attacker could observe network traffic internal to a cluster, they could use the private key to decode API requests that should be protected by TLS sessions, potentially obtaining information they would not otherwise be able to. These certificates are not used for service authentication, so no opportunity for impersonation or active MITM attacks were made possible. • https://bugzilla.redhat.com/show_bug.cgi?id=1892551 • CWE-321: Use of Hard-coded Cryptographic Key CWE-798: Use of Hard-coded Credentials •
CVSS: 6.5EPSS: 0%CPEs: 1EXPL: 0CVE-2020-25655 – open-cluster-management: RBAC bypass may disclose cluster secrets to other users
https://notcve.org/view.php?id=CVE-2020-25655
An issue was discovered in ManagedClusterView API, that could allow secrets to be disclosed to users without the correct permissions. Views created for an admin user would be made available for a short time to users with only view permission. In this short time window the user with view permission could read cluster secrets that should only be disclosed to admin users. Se detectó un problema en la API ManagedClusterView, que podría permitir que sean divulgados secretos a usuarios sin los permisos correctos. Unas vistas creadas para un usuario administrador estarán disponibles durante un breve período de tiempo para los usuarios que solo tengan permiso de visualización. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-25655 https://access.redhat.com/security/cve/CVE-2020-25655 https://bugzilla.redhat.com/show_bug.cgi?id=1888475 • CWE-863: Incorrect Authorization •
