<p>An update that solves one vulnerability can now be installed.</p>
<h2>Description:</h2>
<p>This update for umoci fixes the following issues:</p>
<p>Update to umoci v0.5.0. Upstream changelog is available from</p>
<p><https://github.com/opencontainers/umoci/releases/tag/v0.5.0> bsc#1243388</p>
<p>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</p>
<p>Other changes in this release:</p>
<ul>
<li>Several large reworks and API-related changes to the umoci's overlayfs
support. This is only available to Go API users.</li>
<li>The runtime-spec config.json generated by umoci is updated to be more
modern and work properly with modern runc versions.</li>
<li>The default gzip compression blocksize has been adjusted to match Docker.</li>
<li>zstd-compressed images are now fully supported. Users can explcitily
request the compression algorithm for newly-generated layers with the
--compress option.</li>
</ul>
