1) Oracle Linux 7.1

Oracle Linux update 1 is basically the same as the Red Hat Enterprise Linux 7.1 release that it is based on, though there are a few key differences. For one, in addition to support the same kernel that Red Hat ships, Oracle also has its own Unbreakable Enterprise Kernel (UEK), which is currently based on Linux 3.8, while Red Hat is using a 3.10 kernel.

Additionally, Oracle provides full production support for running Btrfs when using UEK, which is a feature that Red Hat does not officially support yet.

2) pfSense 2.2.1

pfSense is a FreeBSD based operating system that is optimized for router and usage as a firewall. The pfSense 2.2 release debuted on January 23 and was updated to version 2.2.1 on March 17 as a bug fix update.

Among the issues fixed in the update are:

    pfSense-SA-15_02.igmp: Integer overflow in IGMP protocol (FreeBSD-SA-15:04.igmp)
    pfSense-SA-15_03.webgui: Multiple XSS Vulnerabilities in the pfSense WebGUI
    pfSense-SA-15_04.webgui: Arbitrary file deletion vulnerability in the pfSense WebGUI

    FreeBSD-EN-15:01.vt: vt(4) crash with improper ioctl parameters
    FreeBSD-EN-15:02.openssl: Update to include reliability fixes from OpenSSL

Interestingly, pfSense did not update for the recently disclosed FREAK SSL/TLS vulnerability since the disto didn't actually have the vulnerable export ciphers enabled by default.

3) Untangle 11.1

Another firewall networking distribution that has recently been updated is untangle which is based on Debian and leverages an Xfce desktop. The new release includes improved wireless support

Additionally the alerting capabilities of Untangle have been improved with the addition of configurable alerts.

In reports there is now an "Alert Rules" tab where the user can define what alerts are sent and an "Alert Event Log" where past alerts can be viewed. Alerts can be configured via rules that are evaluated on all other events within the system. If an alert rule matches another event that occurs it can log a special event and optionally send an email to administrators. The setup wizard now asks for an email for the admin account which will receive some alerts that are enabled by default (low disk space, etc).
