AI Analysis
Technical Summary
The skopeo utility in Red Hat Enterprise Linux 9 is affected by three security vulnerabilities: a denial of service caused by excessive resource consumption from crafted certificates in the crypto/x509 package (CVE-2025-61729), memory exhaustion during query parameter parsing in the net/url package (CVE-2025-61726), and an unexpected session resumption behavior in the crypto/tls package (CVE-2025-68121). These issues can lead to resource exhaustion or unexpected TLS session behavior. Red Hat has released updated packages to remediate these vulnerabilities as detailed in advisory RHSA-2026:3340.
