------------------------------------------------------------------------- Debian LTS Advisory DLA-4552-1 [email protected] https://www.debian.org/lts/security/ Daniel Leidert April 29, 2026 https://wiki.debian.org/LTS -------------------------------------------------------------------------
Package : node-tar
Version : 6.0.5+ds1+~cs11.3.9-1+deb11u3
CVE ID : CVE-2024-28863 CVE-2026-23745 CVE-2026-24842 CVE-2026-26960
CVE-2026-29786 CVE-2026-31802
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 multiple of the following
vulnerabilties.
CVE-2026-24842
The security check for hardlink entries allows an attacker to craft
a malicious TAR archive that bypasses path traversal protections and
creates hardlinks to arbitrary files outside the extraction
directory.
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.
CVE-2026-31802
An attacker-controlled archive can create a hardlink that points
outside the extraction directory by using a drive-relative link
target.
For Debian 11 bullseye, these problems have been fixed in version
6.0.5+ds1+~cs11.3.9-1+deb11u3.
We recommend that you upgrade your node-tar packages.
