CVE-2023-4154Samba: ad dc password exposure to privileged users and rodcs

samba; Red Hat Red Hat Enterprise Linux 6; Red Hat Red Hat Enterprise Linux 7; Red Hat Red Hat Enterprise Linux 8 Yayım: (3 yıl önce)

Açıklama

A design flaw was found in Samba's DirSync control implementation, which exposes passwords and secrets in Active Directory to privileged users and Read-Only Domain Controllers (RODCs). This flaw allows RODCs and users possessing the GET_CHANGES right to access all attributes, including sensitive secrets and passwords. Even in a default setup, RODC DC accounts, which should only replicate some passwords, can gain access to all domain secrets, including the vital krbtgt, effectively eliminating the RODC / DC distinction. Furthermore, the vulnerability fails to account for error conditions (fail open), like out-of-memory situations, potentially granting access to secret attributes, even under low-privileged attacker influence.

Zayıflık türü (CWE): CWE-787

Veri: CVE.org, NVD, CISA KEV, FIRST EPSS, Ubuntu. Bilgiler kaynaktaki haliyle, İngilizce yayımlanır.

Podman: containers-common: containers-common: default seccomp af_vsock/netlink_audit deny rules bypassable via 32-bit truncation

Red Hat Red Hat Enterprise Linux 10; Red Hat Red Hat Enterprise Linux 8; Red Hat Red Hat Enterprise Linux 9; Red Hat Red Hat Hardened Images

A flaw was found in the default seccomp profile used by Podman via containers-common. Deny rules for AF_VSOCK and NETLINK_AUDIT compared socket arguments with unmasked 64-bit equality. Because the kernel truncates those int arguments to 32 bits, setting upper…

Red Hat Migration Toolkit for Applications 8; Red Hat Migration Toolkit for Virtualization; Red Hat OpenShift Service Mesh 3; Red Hat Red Hat Advanced Cluster Management for Kubernetes 2

A flaw was found in the ansible-core user module. When generate_ssh_key is enabled, User.ssh_key_gen() guards the key files against symlinks but checks the ~/.ssh directory only with os.path.exists(). An unprivileged user on a managed node who replaces their …
