pidgin-otr messaging allows you to have private conversations over instant messaging.
A format string vulnerability has been found in the "log_message_cb()" function in otr-plugin.c.
A remote attacker could possibly execute arbitrary code with the privileges of the process or cause a Denial of Service condition.
There is no known workaround at this time.
All pidgin-otr users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=x11-plugins/pidgin-otr-3.2.1"
