Package        : irssi-text

Vulnerability  : denial of service

Problem-Type   : remote

Debian-specific: no

BugTraq ID     : 5055



The IRC client irssi is vulnerable to a denial of service condition.

The problem occurs when a user attempts to join a channel that has an

overly long topic description.  When a certain string is appended to

the topic, irssi will crash.



This problem has been fixed in version 0.8.4-3.1 for the current

stable stable distribution (woody) and in version 0.8.5-2 for the

unstable distribution (sid).  The old stable distribution (potato) is

not affected, since the corresponding portions of code are not

present.  The same applies to irssi-gnome and irssi-gtk, which don't

seem to be affected as well.



We recommend that you upgrade your irssi-text package.



wget url

	will fetch the file for you

dpkg -i file.deb

        will install the referenced file.



If you are using the apt-get package manager, use the line for

sources.list as given below:



apt-get update

        will update the internal database

apt-get upgrade

        will install corrected packages



You may use an automated update by adding the resources from the

footer to the proper configuration.
