NVD Description

Note: Versions mentioned in the description apply only to the upstream weechat package and not the weechat package as distributed by Debian. See How to fix? for Debian:12 relevant fixed versions and status.

An issue was discovered in WeeChat before 2.7.1 (0.3.4 to 2.7 are affected). When a new IRC message 005 is received with longer nick prefixes, a buffer overflow and possibly a crash can happen when a new mode is set for a nick.
