Title of the patch: Security update for snpguest
Description of the patch: This update for snpguest fixes the following issues: Update to version 0.10.0. Security issues fixed: - CVE-2026-25727: time: parsing of user-provided input by the RFC 2822 date parser can lead to stack exhaustion (bsc#1257927). - CVE-2025-3416: openssl: Use-After-Free in Md::fetch and Cipher::fetch in rust-openssl crate (bsc#1242601). - CVE-2024-12224: idna: idna accepts Punycode labels that do not produce any non-ASCII when decoded (bcs#1243869). Other updates and bugfixes: - Update to version 0.10.0 * fails to generate attestation reports on SEV-SNP guests with firmware API (bsc#1257877). * chore: updating tool version to 0.10.0 * refactor(certs): remove redundant branch in file-write logic * Docs: Adding verify measure, host-data, report-data to docs * verify: verify measurent, host data, and report data attributes from the attestation report. * library: Updating sev library to 7.1.0 * ci: replace deprecated gh actions * feat: multi-format integer parsing for key subcommand arguments * chore(main): remove unused import `clap::arg` * feat(fetch): add fetch crl subcommand * .github/lint: Bump toolchain version to 1.86 * Bump rust version to 1.86 * feat: bumping tool to version 0.9.2 * fix(verify): silence mismatched_lifetime_syntaxes in SnpOid::oid * feat: support SEV-SNP ABI Spec 1.58 (bump sev to v6.3.0) * docs: restore and clarify Global Options section * doc: fix CL argument orders + address recent changes * fix(hyperv): downgrade VMPL check from error to warning * fix(report.rs): remove conflict check between --random flag and Hyper-V * fix(report.rs): Decouple runtime behavior from hyperv build feature * refactor: clarify --platform error message * docs: add Azure/Hyper-V build note for --platform * report: Writing Req Data as Binary (#101) * deps: bump virtee/sev to 6.2.1 (fix TCB-serialization bug) (#99) * Updating SEV library to 6.1.0 and updating version to 0.9.1 * Update version (0.9.0) * HyperV: Fixing report command failure on Azure confidential VM * Removing intird and append requirement for kernel measurements (#93) * Updating to version 6 of library and fixing attestation (#89) * CI: Fixing create_release workflow (#91) * Minor update (0.8.3) * Adding build script * Update preattestation.rs * Fix certificate fetch bug for Turin * Minor update * Update bitfield to 0.15.0 * Update to 0.8.1 * Update asn1-rs and x509-parser * Update to 0.8.0 * key: Fix guest_field_select typo * Adding Turin support and updating ASK cn
