Release Date January 15, 2007
Latest Revision January 15, 2007: 01
Impact normal
Exploitable remote
Package Vulnerable versions Unaffected versions Architecture(s)
net-ftp/oftpd < 0.3.7-r3 >= 0.3.7-r3 All supported architectures

Related bugreports: #159178


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

2.  Impact Information


oftpd is a small, anonymous only ftp daemon.


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.


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

3.  Resolution Information


There is no known workaround at this time.


All oftpd users should upgrade to the latest version:

Code Listing 3.1: Resolution

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