BleedingTooth: Linux Bluetooth Zero-Click Remote Code Execution

Introduction
I noticed that the network subsystem was already being fuzzed extensively by syzkaller, but that subsystems like Bluetooth were less well covered. In general, research on the Bluetooth host attack surface seemed to be quite limited – with most public vulnerabilities in Bluetooth only affecting the firmware or the specification itself, and only allowing attackers to eavesdrop and/or manipulate information.
But what if attackers could take full control over devices? The most prominent examples that demonstrated this scenario were BlueBorne and BlueFrag. I set myself the goal to research the Linux Bluetooth stack, to extend upon BlueBorne’s findings, and to extend syzkaller with the capability to fuzz the ....

Sudo vulnerability could give attackers root access on Linux systems

Sudo vulnerability could give attackers root access on Linux systems
Security researchers have revealed details of a vulnerability in Sudo that could be exploited by an attacker to gain root privileges on a wide range of Linux-based systems.
News of the security flaw was shared by Qualys, and it has been described as perhaps the most significant sudo vulnerability in recent memory . Worryingly, the heap-based buffer overflow bug has existed for almost a decade. It is known as Baron Samedit, tracked as CVE-2021-3156, and affects various versions of Sudo.
See also:
Vulnerable versions of Sudo are legacy versions from 1.8.2 to 1.8.31p2 and all stable versions from 1.9.0 to 1.9.5p1, assuming configurations have not been changed. Writing about its findings, Qualys says that the vulnerability is exploitable by any local user, without authentication . ....

Users of IoT products from three major vendors at risk of DDoS attacks, data leaks

At least nine vulnerabilities in the approach three leading IoT vendors used to implement the open platform communication (OPC) network protocol created conditions that could potentially expose product users to denial-of-service (DoS) attacks, remote code execution, and sensitive data leakage.
The three IoT vendors â Softing Industrial Automation GmbH, Kepware PTC, and Matrikon Honeywell â all provided fixes for their respective products after security firm Claroty privately disclosed them during 2020.
OPC functions as the middleman of operational technology (OT) networks, ensuring operability between industrial control systems (ICS) and proprietary devices, such as programmable logic controllers (PLCs) responsible for the ....
