An update to the OpenWrt 19.07.3 distribution has been prepared, aimed at use in various network devices, such as routers and access points. OpenWrt supports a wide range of platforms and architectures and has a build system that makes cross-compiling easy and convenient, allowing different components to be included in the build. This enables the creation of firmware or disk images tailored to specific tasks, […]
Security researchers from Cisco have disclosed details about a vulnerability (CVE-2020-6096) in the implementation of the memcpy() function in Glibc for the 32-bit ARMv7 platform. The issue arises from improper handling of negative values of the parameter that defines the size of the copied area due to the use of assembler optimizations that manipulate signed 32-bit integers. A call to memcpy() on ARMv7 systems with a negative size results in incorrect comparison of values and writing […]
Previously, we noted that with the introduction of Check Point Maestro, the entry level (in monetary terms) for scalable platforms has significantly decreased. There is no longer a need to purchase chassis solutions. You take exactly as much as you need and add more as necessary without large initial costs (as with chassis solutions). You can see how this is done here. For a long time, orders […]
We won't open America if we claim that virtual machines on new processors are always more efficient than equipment on older generation processors. What's more interesting is that when analyzing systems that seem very similar in technical specifications, the results can be quite different. We confirmed this when we tested Intel processors in our cloud to see which ones provide the greatest […]
Details have been published regarding a vulnerability (CVE-2020-9484) in Apache Tomcat, the open-source implementation of Java Servlet technologies, JavaServer Pages, Java Expression Language, and Java WebSocket. The issue allows for code execution on the server through sending a specially crafted request. The vulnerability has been fixed in releases Apache Tomcat 10.0.0-M5, 9.0.35, 8.5.55, and 7.0.104. For successful exploitation of the vulnerability, the attacker must be able to control the contents and […]
In this article, we will look at a number of optional yet useful settings: using additional names for the manager; connecting authentication via Active Directory; Multipathing; power management; replacing SSL certificates; archiving; host management interface (cockpit); VLANs; HPE-specific features. This article is a continuation, see oVirt in 2 hours Part 1 and part 2. Articles Introduction Installing the manager (ovirt-engine) and […]
Introduction The open source project oVirt is a free enterprise-level virtualization platform. Skimming through Habr, I found that oVirt is not covered here as widely as it deserves. oVirt is actually the upstream for the commercial system Red Hat Virtualization (RHV, previously RHEV), growing under the wing of Red Hat. To avoid confusion, this is not the same as CentOS vs RHEL, the model […]
This article is the next in the oVirt series, starting here. Articles Introduction Installing the manager (ovirt-engine) and hypervisors (hosts) — We are here Additional settings Now, let's look at the issues of the primary installation of the ovirt-engine and ovirt-host components. For more details, the installation processes can always be viewed in the documentation. Content Installing ovirt-engine Installing ovirt-host Adding a node to oVirtN Configuring the network interface Configuring FC […]
An update for the Solaris 11.4 SRU 21 (Support Repository Update) operating system has been published, offering a series of fixes and enhancements for the Solaris 11.4 branch. To install the updates provided in the update, simply execute the 'pkg update' command. The new release includes: A new package driver/network/ethernet/mlxne with drivers for supporting Mellanox ConnectX-4 and ConnectX-5 100Gb Ethernet adapters; Updated printing subsystem components: […]
A group of researchers from Tel Aviv University and the Interdisciplinary Center in Herzliya (Israel) has developed a new NXNSAttack (PDF) method, allowing any DNS resolvers to be used as traffic amplifiers, achieving an amplification factor of up to 1621 times in the number of packets (for every query sent to the resolver, 1621 queries can be sent to the victim's server) and up to 163 times in traffic. The issue […]
