The high-severity vulnerabilities that CISA has added to its patch-now list include SeriousSAM privilege escalation and SMB 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 r...

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.

Matrikon Honeywell is one of three IoT vendors that faced vulnerabilities in their process to implement the open platform communication (OPC) network protocol ahead of a 2020 fix. (Spencer Platt/Getty Images) 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 – Softing Industrial Automation GmbH...
