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"
| OS | Version | Architecture | Package | Version | Filename |
|---|---|---|---|---|---|
| Gentoo | any | all | net-ftp/proftpd | < 1.3.6-r5 | UNKNOWN |
