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
-------------------------------------------------------------------
1 net-ftp/oftpd < 0.3.7-r3 >= 0.3.7-r3
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"
