14 DAY TRIAL // Oracle announced on Tuesday the availability of the fifth update to their Oracle Enterprise Linux 7 operating system series, based on Red Hat's recently released Red Hat Enterprise Linux (RHEL) 7.5 operating system.
Oracle Enterprise Linux 7 Update 5 is now available for download for the x86_64 (64-bit) hardware architecture and brings with it Oracle's Unbreakable Enterprise Kernel (UEK) Release 4 kernel (kernel-uek-4.1.12-112.16.4.el7uek) and a Red Hat Enterprise Linux compatible kernel (kernel-3.10.0-862.el7). Oracle noted that fact that Oracle Enterprise Linux 7.5 remains compatible with apps that have already been certified for the Oracle Linux 7 and Red Hat Enterprise Linux 7.
"Oracle Linux maintains user space compatibility with Red Hat Enterprise Linux (RHEL), which is independent of the kernel version that underlies the operating system. Existing applications in user space will continue to run unmodified on Oracle Linux 7 Update 5 with the UEK Release 4 and no re-certifications are needed for applications already certified with Red Hat Enterprise Linux 7 or Oracle Linux 7," said Avi Miller, Product Management Director, Oracle Linux.
Here's what's new in Oracle Enterprise Linux 7.5
Prominent new features of the Oracle Enterprise Linux 7.5 release include support for the Memory Protection Keys hardware feature that's available on recent Intel processors, provided through a new user-accessible register called PKRU, which contains two separate bits for each key, namely Access Disable and Write Disable. It also adds kernel address-space layout randomization (KASLR) support for KVM (Kernel-based Virtual Machine) guests.
With Oracle Enterprise Linux 7 Update 5, Oracle disabled SSLv3 support in the mod_ssl module of the Apache web server (httpd) to improve the security of SSL and TLS encrypted network connections and restrict the use of various cryptographic cipher suites. Also, this release allows users to unlock network-attached encrypted block devices during the boot process. You can download Oracle Enterprise Linux 7.5 right now through our web portal.
