Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

  - uutils coreutils 尾部工具中的一个漏洞，允许在使用 --follow=name 选项时窃取敏感文件内容。与 GNU 尾部不同，uutils 实现在路径被符号链路替代后仍会继续监控，随后输出链路目标的内容。在有特权用户（如root）监控日志目录的环境中，拥有写权限的本地攻击者可以用指向敏感系统文件的符号链接（如/etc/shadow）替换日志文件，从而导致Tail泄露敏感文件的内容。（CVE-2026-35345）

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且供應商未提供可用的修補程式。

  - uutils coreutils 尾部工具的一個漏洞，允許在使用 --follow=name 選項時外洩敏感檔案內容。與 GNU 尾部不同，uutils 實作在路徑被符號連結取代後仍持續監控，並輸出該連結目標的內容。在有特權使用者（例如 root）監控日誌目錄的環境中，擁有寫入權限的本地攻擊者可以用指向敏感系統檔案的符號連結（例如 /etc/shadow）取代日誌檔案，導致 tail 洩露敏感檔案的內容。（CVE-2026-35345）

請注意，Nessus 的判定取決於廠商所報告的套件是否存在。

Linux/Unix ホストには、ベンダーが提供するパッチが利用できない脆弱性の影響を受ける複数のパッケージがインストールされています。

  - uutils coreutilsのテールユーティリティに脆弱性があり、 --follow=nameオプションを使用すると機密ファイル内容の漏洩が可能となります。GNUの尾部とは異なり、uutilsの実装は、シンボルリンクに置き換えられた後もパスを監視し続け、その後リンクのターゲットの内容を出力します。特権ユーザー(例:root)がログディレクトリを監視している環境では、そのディレクトリに書き込み権限を持つローカル攻撃者がログファイルを機密システムファイルへのシンムリンク(例:/etc/shadow)に置き換え、tailがその機密ファイルの内容を漏らすことがあります。(CVE-2026-35345)

Nessus は、ベンダーによって報告されたパッケージの存在に依存していることに注意してください。

The remote Ubuntu 26.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-9041-1 advisory.

    It was discovered that uutils coreutils mkfifo incorrectly continued processing when a target file already     existed, applying default permissions to the existing file. A local attacker could possibly use this issue     to obtain sensitive information or modify file permissions unexpectedly. (CVE-2026-35341)

    It was discovered that uutils coreutils dd incorrectly suppressed errors during file truncation     operations. A local attacker could possibly use this issue to cause silent data corruption.
    (CVE-2026-35344)

    It was discovered that uutils coreutils tail incorrectly followed symbolic links when using the
    --follow=name option. A local attacker could possibly use this issue to obtain sensitive information.
    (CVE-2026-35345)

    It was discovered that uutils coreutils sort crashed when processing filenames containing non-UTF-8 bytes.
    A local attacker could possibly use this issue to cause a denial of service. (CVE-2026-35348)

    It was discovered that uutils coreutils cp incorrectly preserved setuid and setgid bits when ownership     changes failed. A local attacker could possibly use this issue to gain elevated privileges.
    (CVE-2026-35350)

    It was discovered that uutils coreutils mv failed to preserve file ownership when moving files across file     system boundaries. A local attacker could possibly use this issue to obtain sensitive information or cause     unintended access restrictions. (CVE-2026-35351)

    It was discovered that uutils coreutils mv had a time-of-check to time-of-use race condition in its     extended attribute preservation logic. A local attacker with write access to a directory could possibly     use this issue to modify security labels on unintended files. (CVE-2026-35354)

    It was discovered that uutils coreutils cp had a race condition in its file creation logic, initially     creating destination files with overly permissive modes. A local attacker could possibly use this issue to     obtain sensitive information. (CVE-2026-35357)

    It was discovered that uutils coreutils cp had a time-of-check to time-of-use race condition when handling     symbolic links. A local attacker with write access to a directory could possibly use this issue to obtain     sensitive information. (CVE-2026-35359)

    It was discovered that uutils coreutils touch had a time-of-check to time-of-use race condition during     file creation. A local attacker could possibly use this issue to cause data loss. (CVE-2026-35360)

    It was discovered that uutils coreutils rm failed to recognize trailing slashes on the current directory     path. A local attacker could possibly use this issue to cause data loss. (CVE-2026-35363)

    It was discovered that uutils coreutils mv had a time-of-check to time-of-use race condition during cross-     device operations. A local attacker with write access to a directory could possibly use this issue to     overwrite arbitrary files. (CVE-2026-35364)

    It was discovered that uutils coreutils nohup created its output file with world-readable permissions. A     local attacker could possibly use this issue to obtain sensitive information. (CVE-2026-35367)

    It was discovered that uutils coreutils chroot incorrectly resolved user specifications before dropping     root privileges, allowing Name Service Switch modules to be loaded from the new root directory. A local     attacker with write access to the chroot directory could possibly use this issue to execute arbitrary code     as root. (CVE-2026-35368)

    It was discovered that uutils coreutils ln failed to process filenames containing non-UTF-8 bytes, causing     the utility to exit with an error. A local attacker could possibly use this issue to cause a denial of     service. (CVE-2026-35373)

    It was discovered that uutils coreutils split had a time-of-check to time-of-use race condition in its     input and output file validation. A local attacker with write access to a directory could possibly use     this issue to cause data loss. (CVE-2026-35374)

    It was discovered that uutils coreutils chcon had a time-of-check to time-of-use race condition during     recursive relabeling operations. A local attacker with write access to a directory could possibly use this     issue to modify security labels on unintended files. (CVE-2026-35376)

    It was discovered that uutils coreutils env incorrectly handled backslash sequences within single quotes     when using the -S option. A local attacker could possibly use this issue to cause a denial of service.
    (CVE-2026-35377)

    It was discovered that uutils coreutils install applied setuid and setgid mode bits to destination files     before completing ownership changes. A local attacker could possibly use this issue to gain elevated     privileges. (CVE-2026-93658)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A vulnerability in the tail utility of uutils coreutils allows for the exfiltration of sensitive file     contents when using the --follow=name option. Unlike GNU tail, the uutils implementation continues to     monitor a path after it has been replaced by a symbolic link, subsequently outputting the contents of the     link's target. In environments where a privileged user (e.g., root) monitors a log directory, a local     attacker with write access to that directory can replace a log file with a symlink to a sensitive system     file (such as /etc/shadow), causing tail to disclose the contents of the sensitive file. (CVE-2026-35345)

Note that Nessus relies on the presence of the package as reported by the vendor.
