Debian LTS Advisory DLA-3237-1 [email protected]

Package : node-tar
Version : 4.4.6+ds1-3+deb10u2
CVE ID : CVE-2021-37701 CVE-2021-37712
Debian Bug : 993981

Cache poisoning vulnerabilities were found in node-tar, a Node.js module
used to read and write portable tar archives, which may result in
arbitrary file creation or overwrite.

CVE-2021-37701

It was discovered that node-tar performed insufficient symlink
protection, thereby making directory cache vulnerable to poisoning
using symbolic links.

Upon extracting an archive containing a directory 'foo/bar' followed
with a symbolic link 'foo\\bar' to an arbitrary location, node-tar
would extract arbitrary files into the symlink target, thus allowing
arbitrary file creation and overwrite.

Moreover, on case-insensitive filesystems, a similar issue occurred
with a directory 'FOO' followed with a symbolic link 'foo'.

CVE-2021-37712

Similar to CVE-2021-37701, a specially crafted tar archive
containing two directories and a symlink with names containing
unicode values that normalized to the same value, would bypass
node-tar's symlink checks on directories, thus allowing arbitrary
file creation and overwrite.

For Debian 10 buster, these problems have been fixed in version
4.4.6+ds1-3+deb10u2.

We recommend that you upgrade your node-tar packages.
