Chainguard: multiple code-server packages: security update to 4.140.0-r1

high Tenable Self-Hosted Container Security Plugin ID 472017

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- basic-ftp is an FTP client for Node.js. Prior to 6.2.1, Client.list() can be forced by a malicious or
compromised FTP server to spend quadratic CPU time parsing a directory listing because the RE_LINE
expression in src/parseListUnix.ts backtracks across adjacent variable-length owner and group fields when
a long Unix-style line has a valid prefix but cannot satisfy the later size and date fields. parseList()
selects a parser from the last nonblank line and then applies it to every line, so a normal final line can
select the Unix parser while an earlier crafted line blocks the Node.js event loop and freezes the
process. This issue is fixed in version 6.2.1. (CVE-2026-102990)

Solution

Update the code-server library and its related packages to version 4.140.0-r1 or later.
