RU

Для пакета libssh 0.11.3 найдены CVE-кандидаты по данным NVD/CPE: CVE-2025-14821, CVE-2026-0966. 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.

EN

NVD/CPE candidate CVEs were found for libssh 0.11.3: CVE-2025-14821, CVE-2026-0966. 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-2026-0966

A flaw was found in libssh. The API function ssh_get_hexa() is vulnerable to a denial of service when processing zero-length input. This can be exploited remotely by an attacker during GSSAPI (Generic Security Service Application Program Interface) authentication if the server's logging verbosity is set to SSH_LOG_PACKET (3) or higher. Successful exploitation could lead to a self-Denial of Service of the per-connection daemon process.

CVE-2025-14821

A flaw was found in libssh. This vulnerability allows local man-in-the-middle attacks, security downgrades of SSH (Secure Shell) connections, and manipulation of trusted host information, posing a significant risk to the confidentiality, integrity, and availability of SSH communications via an insecure default configuration on Windows systems where the library automatically loads configuration files from the C:\etc directory, which can be created and modified by unprivileged local users.

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.
