Summary
IBM Integration Bus ships with Node.js for which vulnerabilities were reported
and have been addressed. Vulnerability details are listed below.
Vulnerability Details
CVEID: CVE-2021-37713
DESCRIPTION: Node.js tar module could allow a local attacker to execute
arbitrary code on the system, caused by insufficient logic on Windows systems
when extracting tar files that contained a path that was not an absolute path,
but specified a drive letter different from the extraction target. An attacker
could exploit this vulnerability to create or overwrite arbitrary files and
execute arbitrary code on the system.

Summary

and have been addressed. Vulnerability details are listed below.
Vulnerability Details
CVEID: CVE-2021-37712
DESCRIPTION: Node.js tar module could allow a local attacker to execute
arbitrary code on the system, caused by an arbitrary file creation/overwrite
vulnerability. By creating a directory, and then replacing that directory with
a symlink that had a different apparent name that resolved to the same entry in
the filesystem, an attacker could use an untrusted tar file to symlink into an
arbitrary location and extract arbitrary files into that location to create or
overwrite arbitrary files and execute arbitrary code on the system.
