ProFTPD: Remote code execution — GLSA 201908-16

A vulnerability in ProFTPD could result in the arbitrary execution of code.

Affected packages

net-ftp/proftpd on all architectures
Affected versions < 1.3.6-r5
Unaffected versions >= 1.3.6-r5

Background

ProFTPD is an advanced and very configurable FTP server.

Description

It was discovered that ProFTPD’s “mod_copy” module does not properly restrict privileges for anonymous users.

Impact

A remote attacker, by anonymously uploading a malicious file, could possibly execute arbitrary code with the privileges of the process, cause a Denial of Service condition or disclose information.

Workaround

There is no known workaround at this time.

Resolution

All ProFTPD users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-ftp/proftpd-1.3.6-r5"
