ARM Compiler Buffer Error Vulnerability

ARM Compiler is a tool from ARM UK for compiling and generating applications for the ARM architecture. A security vulnerability exists in Arm Compiler version 5, release 5.06u6, which stems from a bug in the stack protection feature, which is designed to help detect stack-based buffer overflows i...

DEBIAN-CVE-2020-29571

An issue was discovered in Xen through 4.14.x. A bounds check common to most operation time functions specific to FIFO event channels depends on the CPU observing consistent state. While the producer side uses appropriately ordered writes, the consumer side isn't protected against re-ordered read...

CVE-2020-29567

An issue was discovered in Xen 4.14.x. When moving IRQs between CPUs to distribute the load of IRQ handling, IRQ vectors are dynamically allocated and de-allocated on the relevant CPUs. De-allocation has to happen when certain constraints are met. If these conditions are not met when first checke...

FIFO event channels control structure ordering

ISSUE DESCRIPTION A bounds check common to most operation time functions specific to FIFO event channels depends on the CPU observing consistent state. While the producer side uses appropriately ordered writes, the consumer side isn't protected against re-ordered reads, and may hence end up...

infinite loop when cleaning up IRQ vectors

ISSUE DESCRIPTION When moving IRQs between CPUs to distribute the load of IRQ handling, IRQ vectors are dynamically allocated and de-allocated on the relevant CPUs. De-allocation has to happen when certain constraints are met. If these conditions are not met when first checked, the checking CPU m...

The vulnerability in the implementation of the interaction protocol between the “ARM Reliezer” software and the “Communication Server” software of the EKRASMS-SP software suite allows a perpetrator to gain access to user registration data.

The vulnerability of the interaction protocol between the “ARM Reliezer” software and the “Server of Communications” software of the PLC EKRA system is related to the presence of a pre-set password for the database containing user account information. Exploiting this vulnerability could allow an...

Robot Vacuums Suck Up Sensitive Audio in ‘LidarPhone’ Hack

Researchers have uncovered a new attack that lets bad actors snoop in on homeowners’ private conversations – through their robot vacuums. The vacuums, which utilize smart sensors in order to autonomously operate, have gained traction over the past few years. The attack, called “LidarPhone” by...
