Security update for umoci SUSE Patch security@suse.de SUSE Security Team SUSE-SU-2025:02282-1 Final 1 1 2025-07-11T08:34:24Z current 2025-07-11T08:34:24Z 2025-07-11T08:34:24Z cve-database/bin/generate-cvrf.pl 2017-02-24T01:00:00Z Security update for umoci This update for umoci fixes the following issues: Update to umoci v0.5.0. Upstream changelog is available from <https://github.com/opencontainers/umoci/releases/tag/v0.5.0> bsc#1243388 A security flaw was found in the OCI image-spec, where it is possible to cause a blob with one media-type to be interpreted as a different media-type. As umoci is not a registry nor does it handle signatures, this vulnerability had no real impact on umoci but for safety we implemented the now-recommended media-type embedding and verification. CVE-2021-41190 Other changes in this release: * Several large reworks and API-related changes to the umoci's overlayfs support. This is only available to Go API users. * The runtime-spec config.json generated by umoci is updated to be more modern and work properly with modern runc versions. * The default gzip compression blocksize has been adjusted to match Docker. * zstd-compressed images are now fully supported. Users can explcitily request the compression algorithm for newly-generated layers with the --compress option.

In the OCI Distribution Specification version 1.0.0 and prior, the Content-Type header alone was used to determine the type of document during push and pull operations. Documents that contain both "manifests" and "layers" fields could be interpreted as either a manifest or an index in the absence of an accompanying Content-Type header. If a Content-Type header changed between two pulls of the same digest, a client may interpret the resulting content differently. The OCI Distribution Specification has been updated to require that a mediaType value present in a manifest or index match the Content-Type header used during the push and pull operations. Clients pulling from a registry may distrust the Content-Type header and reject an ambiguous document that contains both "manifests" and "layers" fields or "manifests" and "config" fields if they are unable to update to version 1.0.1 of the spec.
