Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

OpenTelemetry-Go is the Go implementation of OpenTelemetry. Versions 1.41.0 and 1.43.0 removed raw-length rejection and it causes `Parse` to process arbitrarily large/invalid baggage headers and log errors, enabling DoS via oversized inputs. Versions 1.42.0 and 1.44.0 fix the issue.
Comment 1 Lokesh Mandvekar 2026-08-13 20:27:58 UTC 
skopeo does not bundle go.opentelemetry.io/otel, therefore it is not affected by CVE-2026-41178.

CVE-2026-41178 is specific to OpenTelemetry-Go's baggage parsing functionality. skopeo-1.24.0-2.fc45 does not vendor this dependency.

Verified with:
$ rpm -q --provides skopeo | grep opentelemetry
(no output - not bundled)

Closing as NOTABUG.
