CVE-2022-37703: Open Source Backup for Linux, Windows, UNIX and OS X

What is Amanda?

AMANDA, the Advanced Maryland Automatic Network Disk Archiver, is a backup solution that allows the IT administrator to set up a single master backup server to back up multiple hosts over network to tape drives/changers or disks or optical media. Amanda uses native utilities and formats (e.g. dump and/or GNU tar) and can back up a large number of servers and workstations running multiple versions of Linux or Unix. Amanda uses a native Windows client to back up Microsoft Windows desktops and servers.

The latest stable version of Amanda, 3.5.2 was released on 20th July 2022. As part of this release, we have addressed unintentional deletions of tape data in the backup environment. Your existing data on tapes will be safe and will not get replaced by your new backup set.
