I often got this error message when I learning about machine learning by Python, recently.

'Object arrays cannot be loaded when allow_pickle=False'

The reason for this message is actually very clearly. In fact, it's just that "allow_pickle" is adjusted to False after Numpy package is upgraded.

Introduction

Today I saw the news and found the sudo tool commonly used in unix-liked operating systems has a heap overflow BUG (number CVE-2021-3156).

At present, it has been confirmed that full root permissions can be obtained in the following version:

  • Ubuntu 20.04（sudo 1.8.31）
  • Debian 10（sudo 1.8.27）
  • Fedora 33（sudo 1.9.2）\

According the news, as well as several discussion forums I have roughly read, almost all of them are suggesting that everyone quickly upgrade the package version. This bug was be found in 2021/01 and was notified to the sudo development group.

And then, I record how to upgrade our sudo package version.
