nbSMTP is an SMTP client suitable to run in chroot jails, in embedded
systems, laptops and workstations.
Niels Heinen discovered a format string vulnerability.
<impact type="normal">
An attacker can setup a malicious SMTP server and exploit this
vulnerability to execute arbitrary code with the permissions of the
user running nbSMTP.
There is no known workaround at this time.
All nbSMTP users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=mail-mta/nbsmtp-1.0&quot;</code>
