Debian is one of the oldest GNU/ Linux distributions and is the basis for many other Linux-based operating systems, including Ubuntu, Kali, MX, and Raspberry Pi OS, among others. This operating system focuses on stability and does not pursue fancy new features, so the release of new versions often takes a long time.
In early June this year, Debian 12 "bookworm" was released, and Debian recently ushered in version 12.1, which mainly fixes multiple security issues such as system user creation.
Debian 12.1 broadly improves the following:
- Properly handle the creation of system users; fix the subdirectory processing problem of equal match
- Fix hang when using Kerberos authenticated LDAP
- Fix the playback problem of custom alarm clock sound
- Fix rendering issues with text uploads
- Add libboost-json1.81.0 missing dependency to libboost-json1.81-dev
- Properly restore POSIX ACLs
- Enable sockets in ConTeXt mtxrun
- Fix buffer overflow vulnerability [CVE-2023-34095]
- Fix CRLF injection [CVE-2023-26130]
- Fix default acquis.yaml to also include Journalctl datasource, but only in ssh.service unit, ensure fetching even without legacy auth.log file; ensure invalid datasources don't cause engine errors
- Security fixes: use-after-free [CVE-2023-34241]; Heap buffer overflow [CVE-2023-32324]
- Configure the full path to ssh
- Bumped Linux kernel ABI to 6.1.0-10; rebuild with suggested updates
- Fix default DNF const PYTHON_INSTALL_DIR
- Fixed several minor vulnerabilities [CVE-2022-2309], [CVE-2023-30570]
- Fixed several memory leak issues
- Improved GTK 4 support
- Fixed several minor issues with Host
Debian 12.1 is essentially a minor fix to Debian 12, the current mainstream version of Debian, which brings thousands of new and updated software packages, support for multiple desktop environments and processor architectures (including 32-bit and 64-bit PCs, ARM, MIPS, and PowerPC), but one of the biggest changes is the upgrade of the Linux kernel from version 5.10 to version 6.1 LTS (with updated drivers, support for new hardware, and long-term support until at least December 2026 moon).
Some other changes in Debian 12 include the reintroduction of Secure Boot on ARM64 systems, support for reading and writing the APFS Apple file system, new artwork, and new versions of desktop environments including Gnome 43, KDE Plasma 5.27, LXDE 11, LXQt 1.2.0, MATE 1.26 and Xfce 4.18.
