http://security.gentoo.org/

Severity:	high
Title:	ProFTPD: Local privilege escalation
Date:	02/13/2007
Bugs:	#158122
ID:	200702-02

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"
