Description Praise Ogwuche 2026-08-13 04:08:01 UTC
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 Dave Dykstra 2026-08-13 16:33:35 UTC
apptainer is indeed using version 1.43.0.  I'm not sure if it is affected by the vulnerability since it is included indirectly through github.com/moby/moby/client.  Include fix in in next release.
