Description
This security bulletin contains information about 1 security vulnerability.
1) Absolute Path Traversal (CVE-ID: CVE-2021-32804)
The vulnerability allows a remote attacker to overwrite arbitrary files on the system.
The vulnerability exists due to a logic issue when file paths contained repeated path roots such as ////home/user/.bashrc. node-tar
would only strip a single path root from such paths. When given an
absolute file path with repeating path roots, the resulting path (e.g. ///home/user/.bashrc) would still resolve to an absolute path, thus allowing arbitrary file creation and overwrite.
Remediation
Install update from vendor's website.
