Introduction to PLCs and Ladder Logic

Introduction We do a lot of client work with ICS, IIoT, and SCADA. We've been to various power plants, factories, electricity substations and they all use the same technology in the form of a PLC. A PLC is a Programmable Logic Controller. PLCs are what keep our Critical National Infrastructure...

USN-4363-1: Linux kernel vulnerabilities

It was discovered that the Serial CAN interface driver in the Linux kernel did not properly initialize data. A local attacker could use this to expose sensitive information kernel memory. CVE-2020-11494 It was discovered that the linux kernel did not properly validate certain mount options to the...

USN-4367-1: Linux kernel vulnerabilities

It was discovered that the btrfs implementation in the Linux kernel did not properly detect that a block was marked dirty in some situations. An attacker could use this to specially craft a file system image that, when unmounted, could cause a denial of service system crash. CVE-2019-19377 It was...

USN-4324-1: Linux kernel vulnerabilities

Al Viro discovered that the vfs layer in the Linux kernel contained a use- after-free vulnerability. A local attacker could use this to cause a denial of service system crash or possibly expose sensitive information kernel memory. CVE-2020-8428 Shijie Luo discovered that the ext4 file system...
