Description

Several issues have been found in weechat, a fast, light and extensible chat client. All issues are about crafted messages, that could result in a buffer overflow and application crash. This could cause a denial of service or possibly have other impact.

For Debian 8

For Debian 8 'Jessie', these problems have been fixed in version
