Ubuntu 18.04 switching back to GNOME, Broadcom WiFi chip vulnerabilities, and Brickerbot malware

Ubuntu 18.04 Default Desktop

In a post on the 5th of April, Canonical and Ubuntu founder Mark Shuttleworth announced the end of investments in Unity8, the phone and convergence shell, as well as Ubuntu 18.04 to ship out with GNOME desktop by default.

Broadcom Vulnerabilities

Millions of Apple and Android devices, which carry the Broadcom wifi chip, are vulnerable to over the air hacking.

Described as a stack buffer overflow, the vulnerability was discovered by Google’s project zero and is said to allow the execution of remote code on the affected devices.

Brickerbot Malware Kills IoT Devices

Similar to Miria, the botnet malware that targets vulnerable IoT devices, Brickerbot uses the same TELNET bruteforce attack vector.

Brickerbot targets Linux based IoT devices running the BusyBox toolkit. Once inside the operating system, the code scrambles onboard memory, flushes IP and NAT tables, sets the outbound firewall rule to drop, and for the final nail in the coffin; tries to wipe all code on the affected devices.

Google: First SHA1 Collision, Cloudflare Memory Leak Incident Report

At they went over the sha-1 collision from last week;
“Hash functions compress large amounts of data into a small message digest. As a cryptographic requirement for wide-spread use, finding two messages that lead to the same digest should be computationally infeasible. Over time however, this requirement can fail due to attacks on the mathematical underpinnings of hash functions or to increases in computational power.

Today, more than 20 years after of SHA-1 was first introduced, we are announcing the first practical technique for generating a collision.”

Cloudflare released a report on the memory leak incident from late last week.
In some circumstances, their edge servers were running past the edge of a buffer and returning memory that contained private information such as, HTTP cookies, authentication tokens and more. Cloudflare went on in the report about the fix and details about the issue. For more:

Ubuntu 16.04.2 LTS released, Arch Linux ending i686 support, AnC side-channel attack, and OpenSSL update.

Arch Linux’s February ISO is to be the last release with i686 support, and will only receive updates for the next nine months. According to it is due to a decreasing lack of popularity among devs and the community. The people at Arch are encouraging anyone still interested to “keep it alive” with some guidance from the Arch team.

Over at Vusec they document a side-channel attack, which can detect which locations in the page table are accessed by the memory management unit. The attack takes advantage of the cache hierarchy of modern processors being shared by untrusted applications. More details in the link below.

OpenSSL 1.1.0 updates to 1.1.0e.
