Red Hat Security Advisory: Red Hat Hardened Images RPMs bug fix and enhancement update
Severity
Low
Notes
Topic: An update for Red Hat Hardened Images RPMs is now available.
Details: This update includes the following RPMs:
caddy:
* caddy-2.11.4-0.1.hum1 (aarch64, x86_64)
* caddy-2.11.4-0.1.hum1.src (src)

A flaw was found in OpenTelemetry-Go. Repeated successful calls to the `ParseFile` function, specifically within `go.opentelemetry.io/otel/schema/v1.0` and `go.opentelemetry.io/otel/schema/v1.1`, can lead to a file descriptor leak. If a consuming application exposes repeated schema parsing to an attacker-controlled path, a remote attacker could exploit this to exhaust the process file descriptor limit, resulting in a Denial of Service (DoS) condition.
