Corrective releases of Firefox 67.0.3 and 60.7.1 have been published, addressing a critical vulnerability (CVE-2019-11707) that could cause the browser to crash when executing malicious JavaScript code. The vulnerability is caused by a type handling issue in the Array.pop method. Access to detailed information is currently restricted. It is also unclear whether the issue is limited to the reported crash or could potentially be exploited for arbitrary code execution by an attacker. Additional information: […]
"Jetpack Pilot" is a "job of the past," it's 60 years old. "Jetpack Developer" - 100 years old. "Instructor of the school course on jetpack construction" is a job of the present, we're doing that now. But what is the profession of the future? Tamper? Archeoprogrammer? Designer of false memories? Blade Runner? A long-time acquaintance of mine who participated in the crowdsourcing for a jetpack engine has now launched his […]
Two years after the cessation of the formation of 32-bit installation images for the x86 architecture, the developers of Ubuntu have decided to fully end the lifecycle of this architecture in the distribution. Starting with the autumn release of Ubuntu 19.10, packages in the repository for the i386 architecture will no longer be created. The last LTS branch for users of 32-bit x86 systems will be Ubuntu 18.04, the support for which will last […]

Cloudflare has launched the League of Entropy service, which is supported by a consortium of several organizations interested in providing high-quality random numbers. Unlike existing centralized systems, the League of Entropy does not rely on a single source and uses entropy generated from multiple unrelated generators managed by different project participants to generate random sequences. […]

Research work is perhaps the most interesting part of our studies. The idea is to try out your chosen direction while still at university. For instance, students from Software Engineering and Machine Learning often pursue research projects in companies (mostly JetBrains or Yandex, but not only). In this post, I will talk about my project in the field of Computer Science. […]
Netflix employees discovered three vulnerabilities in the TCP network stack code. The most serious vulnerability allows a remote attacker to trigger a kernel panic. Several CVE identifiers were attached to these issues: CVE-2019-11477 is classified as a significant vulnerability, while CVE-2019-11478 and CVE-2019-11479 are deemed moderate. The first two vulnerabilities relate to SACK (Selective Acknowledgment) and MSS (Maximum […]
Mozilla developers have disabled the playback of Flash content by default in the nightly builds of Firefox. Starting with Firefox 69, scheduled for September 3, the settings for the Adobe Flash Player plugin will remove the option to enable Flash permanently, leaving only the ability to disable Flash and to individually enable it for specific sites (activation with an explicit click) without remembering the selected mode. In the ESR branches of Firefox […]
The release of DragonFlyBSD 5.6 is now available, an operating system with a hybrid kernel, created in 2003 for the alternative development of the FreeBSD 4.x branch. Key features of DragonFly BSD include the HAMMER distributed versioned filesystem, support for loading 'virtual' kernels as user processes, caching data and metadata from the filesystem on SSDs, context-aware variant symbolic links, and the ability to freeze processes […]
Netflix has identified several critical vulnerabilities in the TCP stacks of Linux and FreeBSD that allow for remote initiation of kernel crashes or excessive resource consumption when processing specially crafted TCP packets (packet-of-death). The issues are caused by errors in the handlers for maximum segment size (MSS) in TCP packets and the selective acknowledgment (SACK) mechanism. CVE-2019-11477 (SACK Panic) […]
