Remote Code Execution via unsafe deserialization in model loaders. Red Hat rates this important (CVSS 7.5). Weakness: CWE-502. Affected products named by the advisory: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 9; Red Hat Hardened Images; Red Hat OpenShift distributed tracing 3.
Arbitrary script execution via improper input sanitization. Red Hat rates this important (CVSS 7.3). Weakness: CWE-79. Affected products named by the advisory: Red Hat Enterprise Linux; OpenShift Pipelines; Red Hat OpenShift Container Platform 4.
Arbitrary file write via path traversal in SCP client. Red Hat rates this important (CVSS 8.1). Weakness: CWE-22. Affected product named by the advisory: Red Hat Enterprise Linux.
Denial of Service via repeated leafnode INFO messages during pre-authentication. Red Hat rates this important (CVSS 7.5). Weakness: CWE-476. Affected products named by the advisory: Red Hat Enterprise Linux; Red Hat Hardened Images.
NATS Server is a high-performance server for NATS.io, the cloud and edge native messaging system. Prior to 2.14.0, 2.12.7, and 2.11.16, when no_auth_user was configured, a parser fast path intended for ordinary client connections could also apply to route or leafnode listeners, allowing an unauthenticated peer to bypass inter-server CONNECT authentication and operate with the privileges associated with that connection type. This issue is fixed in versions 2.14.0, 2.12.7, and 2.11.16. A flaw was found in NATS Server. This allows an unauthenticated attacker on an adjacent network to bypass inter-server authentication. Consequently, the attacker can operate with the privileges of a trusted connection, leading to a high impact on data integrity.
