    Version        : 6.1.13+~cs7.0.5-1+deb12u1
    CVE ID         : CVE-2024-28863 CVE-2026-23745 CVE-2026-26960 CVE-2026-29786

    Multiple vulnerabilities have been discovered in node-tar, a Node.js
    module to read and write portable tar archives.

    CVE-2024-28863

       Generating a large number of sub-folders can consume memory on the
       system and even crash the Node.js client within a few seconds using
       a path with too many sub-folders inside.

    CVE-2026-23745

       When preservePaths is false, the linkpath of Link (hardlink) and
       SymbolicLink entries fail to be sanitized, allowing malicious
       archives to bypass the extraction root restriction, leading to
       arbitrary file overwrites via hardlinks and symlink poisoning via
       absolute symlink targets.

       The fix for this issue introduces CVE-2026-24842 and CVE-2026-31802.
       Both have been fixed subsequently.


    CVE-2026-26960

       An attacker-controlled archive can create a hardlink inside the
       extraction directory that points to a file outside the extraction
       root, enabling arbitrary file read and write as the extracting user.

    CVE-2026-29786

       An attacker-controlled archive can create a hardlink that points
       outside the extraction directory by using a drive-relative link
       target.

    For Debian 12 bookworm, these problems have been fixed in version
    6.1.13+~cs7.0.5-1+deb12u1.

    We recommend that you upgrade your node-tar packages.
