Description

While waiting for the channel synchronization, Irssi may incorrectly
fail to remove destroyed channels from the query list, resulting in use
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).
