A use-after-free was discovered in Irssi 0.8.18 and later when SASL messages
from a server are received in unexpected order. A remote attacker, in control of
an IRC server, could cause a crash in Irssi clients by leveraging this flaw.
Created irssi tracking bugs for this issue:
Affects: fedora-all [bug 1546227]
This issue did not affect the versions of Irssi as shipped with Red Hat Enterprise Linux 6 and 7 as they did not include support for SASL.
