"Multiple vulnerabilities has been found and corrected in irssi :

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-2010-1155).

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 (CVE-2010-1156).

Additionally the updated packages disables the SSLv2 protocol and
enables the SSLv3 and TLSv1 protocols for added security.

The updated packages have been patched to correct these issues."
