IPFire 2.29 Core Update 189 represents a notable enhancement, featuring a security fix, an updated graph for the IPS, and various package updates. This update represents one of the most significant releases to date, delivering a multitude of new firmware files for a range of hardware.

The update serves as a security measure aimed at preventing the IPS process from crashing, thereby safeguarding services operating on the firewall from exposure to the Internet. Improvements have been implemented to enhance the handling of the IPS. These include the introduction of a watcher process to restart the IPS in the event of unexpected crashes, the ability to bypass whitelisted traffic in the iptables ruleset, and the filtering of IPsec traffic. The IPS page now presents IPS throughput categorized into three distinct areas: scanned bandwidth, whitelisted traffic, and bypassed traffic. The Linux firmware has been updated to version 20240811, featuring a marginally increased download size.

IPFire 2.29 - Core Update 189 is now available for testing. It includes a security fix, a new graph for the Intrusion Prevention System (IPS), and numerous package changes.

The upgrade addresses a security flaw in the IPS that might open the firewall and expose services operating on it to the internet. To address this, changes have been made to the IPS's handling, such as a watcher process that restarts it in the event of an unexpected crash, the ability to skip whitelisted traffic in the iptables ruleset, and IPsec traffic filtering. The update also adds a new graph on the IPS page that divides IPS throughput into three categories: scanned bandwidth, whitelisted traffic, and bypass traffic. Linux Firmware version 20240811 includes updates to various firmware for WLAN and Ethernet interfaces, RAID controllers, and other hardware.

CSF, a Stateful Packet Inspection (SPI) firewall, login/intrusion detection, and security program for Linux servers, has been updated. The scripts include a simple SPI iptables firewall script, a daemon process that checks for login authentication failures across several systems, and configurable login failures with distinct log files and regular expression matching. It also features UI connection with cPanel, DirectAdmin, and Webmin, as well as quick version upgrades.

The latest version removes the session IP match check from the DA login and includes an example spamassassin temp file regex.

IPFire 2.29 - Core Update 188 is a big release that includes several changes for users. It features package updates, a new kernel, performance improvements for Quality of Service, better handling of DHCP leases, an enhanced build system, a new version of OpenSSL, and solutions for Intel's most recent CPU vulnerabilities. The version also includes a new method for getting DHCP leases into DNS, allowing devices to be reached by their names rather than a random IP address.

The IPFire build system has been upgraded, resulting in stronger protection from the build system to the host system and vice versa. This increased isolation allows IPFire to be compiled for all architectures on the same machine without causing any negative effects. The version also includes bug fixes, stability and security improvements, as well as a new kernel based on Linux 6.6.47.

IPFire 2.29 - Core Update 187 is now available for testing, with improved protection against Distributed Denial-of-Service attacks and several security patches for OpenSSH, Suricata, and Apache2.

The update enables IPFire to leverage TCP SYN cookies to protect infrastructure from SYN flood assaults, which is especially useful in high-bandwidth applications and cloud deployments. The IP Blocklist feature now supports two additional lists: 3CORESec and Abuse.ch Botnet C2. Vectorscan, a derivative of Intel's Hyperscan library, supports ARM64 architecture and is expected to increase the Intrusion Prevention System's performance. When configured in the most restrictive mode, the firewall generates more rules, and IPsec connections cannot be established using a FQDN as the Local/Remote ID. Unprivileged applications can no longer use the bpf() syscall, and OpenSSH has been updated to version 9.8p1 to address the privileges escalation attack known as regreSSHion.

IPFire 2.29 - Core Update 186 has been released, which includes a new kernel, experimental support for Btrfs, and a number of security and bug updates.

The update is based on Linux 6.6.32 and includes mitigations for Register File Data Sampling in Intel processors, as well as fixes for CPU graph issues. The Raspberry Pi has been supported for CPU frequency scaling, and experimental support for Btrfs allows for data compression and snapshot creation, which may benefit development and rollbacks.

Core Update 185 of IPFire 2.29 has been released, which includes a new IPFire intrusion prevention system (IPS) that is based on Suricata 7 as well as bug fixes and package updates. Support for HTTP/2, deflate compression, byte-ranges, TLS client certificates, IKEv1, PostgreSQL protocol, BitTorrent parser, QUICv1 and GQUIC, and Linux Landlocked — all of which are designed to prevent damage — are included in the update. In addition to this, it adds ThreatFox Indicators of Compromise Rules from abuse.ch, fixes a vulnerability that could have caused a denial of service, and removes the PT Attack and Secureworks rule sets.

Andres Freund has discovered that the upstream XZ repository and the XZ tarballs have been backdoored. The majority of Linux distributions that are affected by this issue are either very new or rolling release distributions. A brief summary of all the most recent updates is as follows:

XZ-Utils Security Update for Debian Testing
XZ Utils Security Advisory for Gentoo
XZ Security Update for Arch Linux
XZ-Utils Update for Kali Linux
XZ Security Issue in Fedora Linux 40 and Rawhide

Core Update 185 of IPFire 2.29 has been made available for testing. Bug fixes and package updates have been implemented in the most recent version of the IPFire intrusion prevention system (IPS). The Intrusion Prevention System, Suricata 7, now supports HTTP/2, deflate compression, byte-ranges, TLS client certificates, IKEv1, PostgreSQL protocol, BitTorrent parser, QUICv1, and GQUIC. Additionally, it is compatible with more than one protocol. As an additional measure to prevent damage, Suricata is locked down with Linux Landlocked. Additionally, it is slightly more memory efficient.

In a blog post, Alan Pope discussed a scam that is currently taking place in the Canonical Snap store, which involves the use of fake Bitcoin wallet applications. Exodus-build-96567 is the name of the application that is published by the publisher digisafe00000, which appears to be not very legitimate. The application can be found in searches conducted within the desktop graphical storefront known as "Ubuntu Software" or "App Centre." However, the app does not provide any information about its functionality, despite the fact that it claims to "Secure, Manage, and Swap all of your favorite assets."
