CVE-2010-1155
Irssi before 0.8.15, when SSL is used, does not verify that the server
hostname matches a domain name in the subject's Common Name (CN) field
or a Subject Alternative Name field of the X.509 certificate, which
allows man-in-the-middle attackers to spoof IRC servers via an
arbitrary certificate.

CVE-2010-1156
core/nicklist.c in Irssi before 0.8.15 allows remote attackers to
cause a denial of service (NULL pointer dereference and application
crash) via vectors related to an attempted fuzzy nick match at the
instant that a victim leaves a channel.");
