Special cartridges with heat-shrink tubing for dymo and brother label writers

Posted by jpluimers on 2023/04/26

Labeling cables is important, especially when you have a lot of them, and it is tough:

  1. Paper and plastic tables tend to loosen over time.
  2. Numbers or letters you can snap on only work on thicker cables and over time tend to break loose (due to plasticisers evaporating).
  3. Permanent markers are less permanent and fade over time.

Hopefully heat-shrink tubing you can print on with either Dymo or Brother laber writers will outlast 3. At least they won’t loosen like 2. and 1.

So I was glad that [Archive] Jilles🏳️‍🌈 (@jilles_com) / Twitter started a thread, which I tried to help keeping coherent.

Some of the messages:

VMware fixes critical zero-day Workstation/Player/Fusion exploit revealed at Pwn2Own

Posted by jpluimers on 2023/04/26

A less clickbaity title than most articles today as the below only applies to the VMware hypervisors running on MacOS and Windows.

The last Pwn2Own Zero Day Initiative revealed two major issues that allow a virtual machine to either execute code or read hypervisor memory on the VMware Workstation/Player/Fusion host:

  1. [Wayback/Archive] NVD – CVE-2023-20869

    VMware Workstation (17.x) and VMware Fusion (13.x) contain a stack-based buffer-overflow vulnerability that exists in the functionality for sharing host Bluetooth devices with the virtual machine.

  2. [Wayback/Archive] NVD – CVE-2023-20870

    VMware Workstation and Fusion contain an out-of-bounds read vulnerability that exists in the functionality for sharing host Bluetooth devices with the virtual machine.

Both issues have been fixed now, so be sure to deploy the fixes or, if you can’t, apply the workarounds.
