|
## General (All backends should apply these steps)
|
|
|
|
### Update `/etc/iredmail-release` with new iRedMail version number
|
|
|
|
iRedMail stores the release version in `/etc/iredmail-release` after
|
|
installation, it's recommended to update this file after you upgraded iRedMail,
|
|
so that you can know which version of iRedMail you're running. For example:
|
|
|
|
```
|
|
0.9.7
|
|
```
|
|
|
|
### Upgrade Roundcube webmail to the latest stable release (1.2.4)
|
|
|
|
> Roundcube 1.2.4 fixes a security issue, all users are encouraged to upgrade
|
|
> it as soon as possible. For more details about this release, please check
|
|
> Roundcube [release note](https://github.com/roundcube/roundcubemail/releases/tag/1.2.4).
|
|
|
|
Please follow Roundcube official tutorial to upgrade Roundcube webmail to the
|
|
latest stable release immediately:
|
|
|
|
* [How to upgrade Roundcube](https://github.com/roundcube/roundcubemail/wiki/Upgrade).

|
### Fixed: incorrect session.save_path in php-fpm pool config file on RHEL/CentOS
|
|
|
|
!!! attention
|
|
|
|
This is applicable to RHEL/CentOS system, and Nginx web server.
|
|
|
|
iRedMail-0.9.6 doesn't set path for `session.save_path` parameter in php-fpm
|
|
pool config file `/etc/php-fpm.d/www.conf`, please fix it with steps below:
|
|
|
|
* Open file `/etc/php-fpm.d/www.conf`, find line:
|
|
|
|
```
|
|
php_value[session.save_path] = "/var/lib/php/session"
|
|
```
|
|
|
|
* The directory name should be `sessions` (ends with `s`), not `session`. So
|
|
please change it to:
|
|
|
|
```
|
|
php_value[session.save_path] = "/var/lib/php/sessions"
|
|
```
|
|
|
|
* Restarting php-fpm service is required:
|
|
|
|
```
|
|
service php-fpm restart
|
|
```
|
|
|
|
### Fixed: Improper Fail2ban filter which causes incorrect ban
|
|
|
|
Please open file `/etc/fail2ban/filter.d/dovecot.iredmail.conf`, remove line
|
|
below:
|
|
|
|
```
|
|
\(no auth attempts in .* rip=<HOST>
|
|
```
|
|
|
|
Then restart or reload Fail2ban service.

### Fixed: Avoid possible backdooring mysqldump backups
|
|
|
|
For more details about this backdooring mysqldump backup issue, please read
|
|
blog post:
|
|
|
|
* [[CVE-2016-5483] Backdooring mysqldump backups](https://blog.tarq.io/cve-2016-5483-backdooring-mysqldump-backups/).
|
|
|
|
Steps to fix it:
|
|
|
|
* Open the daily MySQL backup script, it's `/var/vmail/backup/backup_mysql.sh`
|
|
by default. if you use different storage directory during iRedMail
|
|
installation, you can find the base directory with command `postconf virtual_mailbox_base`.
|
|
|
|
* Find variable name `CMD_MYSQLDUMP` like below:
|
|
|
|
```
|
|
export CMD_MYSQLDUMP="mysqldump ..."
|
|
```
|
|
|
|
* Make sure it has argument `--skip-comments` like below:
|
|
|
|
```
|
|
export CMD_MYSQLDUMP="mysqldump ... --skip-comments"
|
|
```
|
|
|
|
* Save your change. That's it.
