SCA: security update for ftp-srv (GHSA-pmw4-jgxx-pcq9)

critical Tenable Self-Hosted Container Security Plugin ID 431986

Description

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

- ftp-srv is an open-source FTP server designed to be simple yet configurable. In ftp-srv before version
4.4.0 there is a path-traversal vulnerability. Clients of FTP servers utilizing ftp-srv hosted on Windows
machines can escape the FTP user's defined root folder using the expected FTP commands, for example, CWD
and UPDR. When windows separators exist within the path (`\`), `path.resolve` leaves the upper pointers
intact and allows the user to move beyond the root folder defined for that user. We did not take that into
account when creating the path resolve function. The issue is patched in version 4.4.0 (commit
457b859450a37cba10ff3c431eb4aa67771122e3). (CVE-2020-26299)
