Red Hat Security Advisory: Red Hat Hardened Images RPMs bug fix and enhancement update
Severity
Critical
Notes
Topic: An update for Red Hat Hardened Images RPMs is now available.
Details: This update includes the following RPMs:
grafana13.2:
* grafana13.2-13.2.0-0.1.1.hum1 (aarch64, x86_64)
* grafana13.2-13.2.0-0.1.1.hum1.src (src)

A flaw was found in nanoid (Nano ID), a JavaScript library used for generating unique identifiers. This vulnerability allows an attacker to cause a Denial of Service (DoS) by providing a negative size input to the customAlphabet or nanoid functions within the library's non-secure module. When a negative size is provided, these functions enter an infinite loop, causing the application to hang indefinitely and disrupting service availability.

Threats
Impact
Important
A flaw was found in kin-openapi. This vulnerability allows a remote attacker to bypass authentication checks. Specifically, the system incorrectly handles missing authentication configurations, substituting them with a function that does not verify user credentials. This enables unauthorized access to protected resources that should require proper authentication, compromising the application's security.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
