- Ars Technica reports one team "compromised Microsoft's heavily fortified Edge browser in a way that escapes a VMware Workstation virtual machine it runs in... by exploiting a heap overflow bug in Edge, a type confusion flaw in the Windows kernel and an uninitialized buffer vulnerability in VMware."
- Digital Trends reports "Samuel Grob and Niklas Baumstark used a number of logic bugs to exploit the Safari browser and eventually take root control of the MacOS on a MacBook Pro, [and] impressed onlookers even more by adding a custom message to the Touch Bar which read: "pwned by niklasb and saelo."
- Ubuntu 16.10 Linux was also successfully attacked by exploiting a flaw in the Linux 4.8 kernel, "triggered by a researcher who only had basic user access but was able to elevate privileges with the vulnerability to become the root administrative account user..." reports eWeek. "Chaitin Security Research Lab didn't stop after successfully exploiting Ubuntu. It was also able to successfully demonstrate a chain of six bugs in Apple Safari, gaining root access on macOS."
- Another attacker "leveraged two separate use-after-free bugs in Microsoft Edge and then escalated to SYSTEM using a buffer overflow in the Windows kernel."
None of the attendees registered to attempt an attack on the Apache Web Server on Ubuntu 16.10 Linux, according to eWeek, but the contest's blog reports that "We saw a record 51 bugs come through the program. We paid contestants $833,000 USD in addition to the dozen laptops we handed out to winners. And, we awarded a total of 196 Master of Pwn points."
-Support for Raspberry Pi Zero.
-Initial DRM/KMS support for NVIDIA graphics cards via nouveau (Disabled by default. Uncomment nouveau and nouveaufb in your kernel config to test).
The addition of vioscsi, a driver for the Google Compute Engine disk.
-Linux compatibility improvements, allowing, e.g., the use of Adobe Flash Player 24.
-wm(4): C2000 KX and 2.5G support; Wake On Lan support; 82575 and newer SERDES based systems now work.
-ODROID-C1 Ethernet now works.
-Numerous bug fixes and stability improvements.

Bug-Squashing Parties have been scheduled this week in Germany and Brazil, with at least two more happening in May in Paris and Zurich, and for current Debian contributors, "Debian is willing to reimburse up to $100 (or equivalent in your local currency) for your travel and accommodation expenses for participating in Bug Squashing Parties..." writes Dogguy, adding "If there are no Bug Squashing Parties next to your city, can you organize one?"
Note that once users' PCs are compromised, the hackers can do anything on the PCs. This solution only prevents from Notepad++ loading a CIA homemade DLL. It doesn't prevent your original notepad++.exe from being replaced by modified notepad++.exe while the CIA is controlling your PC.
The update also includes "a lot of enhancements and bug-fixes," and if no critical issues are found, "Auto-updater will be triggered in few days."
What's perhaps even more worrying is that when Trustwave contacted DblTek regarding the backdoor last autumn -- multiple times -- patched firmware was eventually released at the end of December. However, rather than removing the flaw, the vendor simply made it more difficult to access and exploit. And further correspondence with the Chinese company has apparently fallen on deaf ears.
The firmware with the hole "is present on almost every GSM-to-VoIP device which DblTek makes," and Trustwave "found hundreds of these devices on the net, and many other brands which use the same firmware, so are equally open to exploit."
"According to Google researchers, attackers could leverage malformed EMF files to expose data found in the victim's memory, which can then be leveraged to bypass ASLR protection and execute code on the user's computer... ACROS Security has issued a temporary patch that can be applied to Windows computers via its product, called 0patch, a platform that applies fixes for zero-days, unpatched vulnerabilities, end-of-life and unsupported products, for legacy OSes, vulnerable 3rd party components, and customized software." When Microsoft issues an official update, the temporary patch will stop working immediately.
- One-to-one video calls can be made from Linux to Skype users on the latest versions of Skype for Android, iOS, Windows, and Mac.
- Calls to mobiles and landlines with Skype credit.

- Unity launcher now shows the number of unread conversations.
- Online contacts in contact list now include Away and Do Not Disturb statuses.
Details about CVE-2017-0037 are available in Google's bug report, along with proof-of-concept code. The PoC code causes a crash of the exploited browser, but depending on the attacker's skill level, more dangerous exploits could be built... Besides the Edge and IE bug, Microsoft products are also plagued by two other severe security flaws, one affecting the Windows GDI component and one the SMB file sharing protocol shipped with all Windows OS versions...
Google's team notified Microsoft of the bug 90 days ago, only disclosing it publicly on Friday.
Another news story is that based on the theoretical incomplete description of the SHA-1 collision attack published by Google just two days ago, people have managed to recreate the attack in practice and now you can download a Python script which can create a new PDF file with the same SHA-1 hashsum using your input PDF. The attack is also implemented as a website which can prepare two PDF files with different JPEG images which will result in the same hash sum.
Of course, the stats are based on vulnerabilities announced in Microsoft Security Bulletins, but there's an overwhelming pattern. Turning off admin rights mitigated the vast majority of vulnerabilities, whether it was Windows Server (90%) or older versions of Microsoft Office (99%). And turning off admin rights in Office 2016 mitigated 100% of its vulnerabilities.
And the company's CTO also told Reuters that "We've seen absolutely no evidence that this has been exploited. It's very unlikely that someone has got this information... We do not know of anybody who has had a security problem as a result of this." Nevertheless, Fortune warns that "So many sites were vulnerable that it doesn't make sense to review the list and change passwords on a case-by-case basis." Some sites are now even resetting every user's password as a precaution, while site operators "are also being advised to wipe their sites' cookies and security certificates, and perform their own web searches to see if site data leaked." But I'd like to know what security precautions are being taken by Slashdot's readers?

This severe flaw in the browser security model affects only Internet Explorer 11, which unfortunately is the second most used browser version, after Chrome 55, with a market share of over 10%. Even worse for IE11 users, there's no fix available for this issue because the researcher has decided to stop reporting bugs to Microsoft after they've ignored many of his previous reports. For IE11 users, a demo page is available here.
