Для этого нужен надежный инструмент, который может работать с любыми политиками и валидировать действия клиентов в кластерах Kubernetes. Читать дальше →
** DISPUTED ** Styra Open Policy Agent (OPA) Gatekeeper through 3.7.0 mishandles concurrency, sometimes resulting in incorrect access control. The data replication mechanism allows policies to access the Kubernetes cluster state. During data replication, OPA/Gatekeeper does not wait for the replication to finish before processing a request, which might cause inconsistencies between the replicated resources in OPA/Gatekeeper and the resources actually present in the cluster. Inconsistency can later be…
In GateKeeper::MintAuthToken of gatekeeper.cpp in Android 7.1.1, 7.1.2, 8.0, 8.1 and 9, there is possible memory corruption due to a double free. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.
This was addressed with additional checks by Gatekeeper on files mounted through a network share. This issue is fixed in macOS Catalina 10.15.3. Searching for and opening a file from an attacker controlled NFS mount may bypass Gatekeeper.
