Для пакета openssh 9.9p2 найдены CVE-кандидаты по данным NVD/CPE: CVE-2023-51767, CVE-2026-35385, CVE-2026-35386, CVE-2026-35414. Требуется triage security-team.

Проверить применимость CVE к сборке НАЙС.ОС, сопоставить с upstream/vendor advisory, определить статус affected/fixed/not_affected и при необходимости подготовить обновление пакета.

Рекомендуемое действие: needs_triage

Подсказка по целевой версии: -

Проверки: Проверить сборку RPM, обновление пакета, совместимость зависимостей, service/CLI smoke tests и регрессионные сценарии по классу пакета.

Риски: Автоматическое совпадение NVD/CPE не является финальным вердиктом по НАЙС.ОС.

NVD/CPE candidate CVEs were found for openssh 9.9p2: CVE-2023-51767, CVE-2026-35385, CVE-2026-35386, CVE-2026-35414. Security-team triage is required.

Verify CVE applicability to the NiceOS build, compare with upstream/vendor advisories, set affected/fixed/not_affected status, and prepare a package update if required.

Recommended action: needs_triage

Target version hint: -

Tests: Run RPM build, package upgrade, dependency compatibility, service/CLI smoke tests, and package-class-specific regression tests.

Risks: An automatic NVD/CPE match is not the final NiceOS vulnerability verdict.

Descriptions

CVE-2026-35385

In OpenSSH before 10.3, a file downloaded by scp may be installed setuid or setgid, an outcome contrary to some users' expectations, if the download is performed as root with -O (legacy scp protocol) and without -p (preserve mode).

CVE-2026-35386

In OpenSSH before 10.3, command execution can occur via shell metacharacters in a username within a command line. This requires a scenario where the username on the command line is untrusted, and also requires a non-default configurations of % in ssh_config.

CVE-2026-35414

OpenSSH before 10.3 mishandles the authorized_keys principals option in uncommon scenarios involving a principals list in conjunction with a Certificate Authority that makes certain use of comma characters.

CVE-2023-51767

OpenSSH through 10.0, when common types of DRAM are used, might allow row hammer attacks (for authentication bypass) because the integer value of authenticated in mm_answer_authpassword does not resist flips of a single bit. NOTE: this is applicable to a certain threat model of attacker-victim co-location in which the attacker has user privileges. NOTE: this is disputed by the Supplier, who states "we do not consider it to be the application's responsibility to defend against platform architectural weaknesses."

Maintainer checklist

Verify whether each CVE applies to the NiceOS build.
Compare NVD data with upstream/vendor advisory.
Set final NiceOS status: affected, fixed, not_affected, false_positive, deferred, or not_in_cloud_image.
If affected, decide update/backport strategy according to package policy class.
Run package-class-specific build, upgrade and regression tests.
Add/update niceos_cve_triage entry.
Create NICE-SA advisory if a security update is shipped.
