ircII is a popular text-mode IRC client.

II.  $BLdBj$N>\:Y(B - Problem Description

ircII version 4.4 contained a remotely-exploitable buffer overflow in
the /DCC CHAT command which allows remote users to execute arbitrary
code as the client user.

The bug was originally reported in 1997 in a much older version of
ircII, but was apparently not corrected at the time, and the problem
was recently rediscovered independently. Development on the version of
ircII previously in ports ceased several years ago, and has been taken
up by a new group who have fixed this problem (and possibly
others). FreeBSD now provides this new version of ircII.

The ircII port is not installed by default, nor is it "part of
FreeBSD" as such: it is part of the FreeBSD ports collection, which
contains over 3200 third-party applications in a ready-to-install
format. FreeBSD 4.0 did not ship with the ircII package available
because this vulnerability was reported to us late in the release
cycle and it was not possible to upgrade the port in time.

FreeBSD makes no claim about the security of these third-party
applications, although an effort is underway to provide a security
audit of the most security-critical ports.

If you have not chosen to install the ircII port/package, then your
system is not known to be vulnerable to this problem, although there
are several other IRC clients which are derived from ircII including
Epic and BitchX. At this time it is unknown whether other clients are
vulnerable to this problem.

I.   $BGX7J(B - Background

healthd is a small utility for monitoring the temperature, fan speed
and voltage levels of certain motherboards.

II.  $BLdBj$N>\:Y(B - Problem Description

healthd v0.3 installs a utility which is setuid root in order to
monitor the system status. This utility contains a trivial buffer
overflow which allows an unprivileged local user to obtain root
privileges on the system.

The healthd port is not installed by default, nor is it "part of
FreeBSD" as such: it is part of the FreeBSD ports collection, which
contains over 3200 third-party applications in a ready-to-install
format. The ports collection shipped with FreeBSD 4.0 contains this
problem since it was discovered after the release.

FreeBSD makes no claim about the security of these third-party
applications, although an effort is underway to provide a security
audit of the most security-critical ports.

III. $B1F6AHO0O(B - Impact

A local user can obtain root privileges by exploiting a vulnerability
in the healthd utility.

system is not vulnerable.

3) download a new port skeleton for the healthd port from:

and use it to rebuild the port.
