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"
