Security update for yq
This security update for the yq tool addresses multiple vulnerabilities primarily in the golang. org/x/net packages related to HTML parsing and IDNA handling. The issues include multiple parsing problems in HTML files and a failure to reject ASCII-only Punycode-encoded labels, which can lead to validation bypass and privilege escalation. The vulnerabilities affect specific SUSE versions of yq on aarch64 and i586 architectures. The update fixes six CVEs: CVE-2026-25680, CVE-2026-25681, CVE-2026-27136, CVE-2026-39821, CVE-2026-42502, and CVE-2026-42506. No known exploits in the wild have been reported.
