mdeslaur | the fix for this issue changes default behaviour and will possibly break existing installations and scripts. Furthermore, other packages in the archive need to be changed to work with the new behaviour, see the Debian advisory for more info: https://www.debian.org/security/2016/dsa-3628 Due to the change in behaviour, we will not be fixing this issue in perl in Ubuntu 12.04 LTS, Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. |
