Red Hat Security Advisory: skopeo security update
The skopeo command lets you inspect images from container image registries, get images and image layers, and use signatures to create and verify files. Security Fix(es): * crypto/x509: golang: Denial of Service due to excessive resource consumption via crafted certificate (CVE-2025-61729) * golang: net/url: Memory exhaustion in query parameter parsing in net/url (CVE-2025-61726) * crypto/tls: Unexpected session resumption in crypto/tls (CVE-2025-68121) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
