Severity:normal
Title:oftpd: Denial of Service
Date:01/15/2007
Bugs: #159178
ID:200701-09

Synopsis

An assertion in oftpd could lead to a denial of service vulnerability.

Background

oftpd is a small, anonymous only ftp daemon.

Affected packages

Package Vulnerable Unaffected Architecture(s)
net-ftp/oftpd < 0.3.7-r3 >= 0.3.7-r3 All supported architectures

Description

By specifying an unsupported address family in the arguments to a LPRT or LPASV command, an assertion in oftpd will cause the daemon to abort.

Impact

Remote, unauthenticated attackers may be able to terminate any oftpd process, denying service to legitimate users.

Workaround

There is no known workaround at this time.

Resolution

All oftpd users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-ftp/oftpd-0.3.7-r3"
