Synopsis
A flaw in ProFTPD may allow a local attacker to obtain root privileges.Background
ProFTPD is a powerful, configurable, and free FTP daemon.
Affected packages
Package | Vulnerable | Unaffected | Architecture(s) |
---|---|---|---|
net-ftp/proftpd | < 1.3.1_rc1 | >= 1.3.1_rc1 | All supported architectures |
Description
A flaw exists in the mod_ctrls module of ProFTPD, normally used to allow FTP server administrators to configure the daemon at runtime.
Impact
An FTP server administrator permitted to interact with mod_ctrls could potentially compromise the ProFTPD process and execute arbitrary code with the privileges of the FTP Daemon, which is normally the root user.
Workaround
Disable mod_ctrls, or ensure only trusted users can access this feature.
Resolution
All ProFTPD users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-ftp/proftpd-1.3.1_rc1"
