CVE-2016-7553 (opens in a new tab)How to fix?
Upgrade Debian:8 irssi to version 0.8.17-1+deb8u2 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream irssi package and not the irssi package as distributed by Debian.
See How to fix? for Debian:8 relevant fixed versions and status.
The buf.pl script before 2.20 in Irssi before 0.8.20 uses weak permissions for the scrollbuffer dump file created between upgrades, which might allow local users to obtain sensitive information from private chat conversations by reading the file.
