Для пакета binutils 2.45 найдены CVE-кандидаты по данным NVD/CPE: CVE-2025-69649, CVE-2025-69650, CVE-2026-3441, CVE-2026-3442, CVE-2026-6846. 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 binutils 2.45: CVE-2025-69649, CVE-2025-69650, CVE-2026-3441, CVE-2026-3442, CVE-2026-6846. 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-2026-6846

A flaw was found in binutils. A heap-buffer-overflow vulnerability exists when processing a specially crafted XCOFF (Extended Common Object File Format) object file during linking. A local attacker could trick a user into processing this malicious file, which could lead to arbitrary code execution, allowing the attacker to run unauthorized commands, or cause a denial of service, making the system unavailable.

CVE-2025-69649

GNU Binutils thru 2.46 readelf contains a null pointer dereference vulnerability when processing a crafted ELF binary with malformed header fields. During relocation processing, an invalid or null section pointer may be passed into display_relocations(), resulting in a segmentation fault (SIGSEGV) and abrupt termination. No evidence of memory corruption beyond the null pointer dereference, nor any possibility of code execution, was observed.

CVE-2025-69650

GNU Binutils thru 2.46 readelf contains a double free vulnerability when processing a crafted ELF binary with malformed relocation data. During GOT relocation handling, dump_relocations may return early without initializing the all_relocations array. As a result, process_got_section_contents() may pass an uninitialized r_symbol pointer to free(), leading to a double free and terminating the program with SIGABRT. No evidence of exploitable memory corruption or code execution was observed; the impact is limited to denial of service. NOTE: this is disputed by third parties because the observed behavior occurred only in pre-release code and did not affect any tagged version.

CVE-2026-3441

A flaw was found in GNU Binutils. This heap-based buffer overflow vulnerability, specifically an out-of-bounds read in the bfd linker, allows an attacker to gain access to sensitive information. By convincing a user to process a specially crafted XCOFF object file, an attacker can trigger this flaw, potentially leading to information disclosure or an application level denial of service.

CVE-2026-3442

A flaw was found in GNU Binutils. This vulnerability, a heap-based buffer overflow, specifically an out-of-bounds read, exists in the bfd linker component. An attacker could exploit this by convincing a user to process a specially crafted malicious XCOFF object file. Successful exploitation may lead to the disclosure of sensitive information or cause the application to crash, resulting in an application level denial of service.

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.
