after free conditions when updating the state later on (CVE-2017-15227).

When installing themes with unterminated color formatting sequences,
Irssi may access data beyond the end of the string. (CVE-2017-15228).

Certain incorrectly formatted DCC CTCP messages could cause NULL pointer
dereference (CVE-2017-15721).

In certain cases Irssi may fail to verify that a Safe channel ID is long
enough, causing reads beyond the end of the string (CVE-2017-15722).

Overlong nicks or targets may result in a NULL pointer dereference while
splitting the message (CVE-2017-15723).");
