Description Andrej Nemec 2016-09-26 09:08:19 UTC

An information disclosure vulnerability was found in the buf.pl core script for irssi. Other users on the same machine may be able to retrieve the whole window contents after /UPGRADE when the buf.pl script is loaded. Furthermore, this dump of the windows contents is never removed afterwards.
