Linux Security News: Linux 3.13, systemrescumcm 4, and BackBox 3.13

1) Linux 3.13

Linus Torvalds released Linux Kernel 3.13 some time ago as the opening ceremony in 2014. By convention, this version updates a large number of drivers.

In addition, Linux Kernel 3.13 includes nftable, which is the successor of the famous iptables. From the submitted code, nftables continues to use the existing netfilter hooks, Connection Tracing System, NAT subsystem, transparent proxy engine, log infrastructure, and user space package arrangement facilities.

"In short, nftables provides four 128-bit General registers and one special register to save the conclusion," said the code commit comments, "And nftables inherits the concepts of iptables" table/chain/rule object ", but provides more flexible configuration methods. It also contains the unknown data type Architecture Supported by the original ing."
It is worth noting that NFC (Near-Field Communication) payment protocol is also supported this time.
"Using NFCCMDSEThe I/O Command sends the ISO07816 application protocol data unit to an NFC embedded security device, "Intel Developer Samuel Ortiz wrote in his submission:" the feedback is also sent through NFCCMDSEIO is returned to the user space ."

2) System Rescue CD 4.0.0

Most people use Linux as a server or desktop system. In fact, we can also use a Linux system to rescue a non-* nix system.

In the Linux release used to restore the system and data, the popular one is "systemrescumcm", which was updated to version 4.0.0 last week.

The following are its update records:

• Standard kernel: LTS linux-3.10.25 with 32-bit rescue32 and 64-bit rescue64)
• Backup kernel: the latest stable linux-3.12.7 (kernel images include 32-bit altker32 and 64-bit altker64)
• XOrg graphic environment and driver update to xorg-server-1.14.3
• GParted is updated to 0.6.2 (online repartition function is added)
• Btrfs toolset updated to sys-fs/btrfs-progs-3.12

(3) BackBox 3.13

Linux is also a powerful weapon in the hands of security experts, and BackBox is a security-focused Linux release (BackBox mainly targets security assessment and penetration testing-Translator's note ). The latest version of BackBox updates a large number of components. It is strange that it uses the Linux 3.13 kernel instead of the latest Linux 3.11 kernel.

Currently, the BackBox release can update security tools in anonymous mode.
