Calendar Grey September 22, 2024
Dist Fedora Esm H88
Fedora's latest security patch for less tackles CVE-2024-32487, a serious command injection vulnerability. Important advisory information provided.
Security fix for CVE-2024-32487 - less with LESSOPEN mishandles \n in paths

Summary

The less utility is a text file browser that resembles more, but has

more capabilities. Less allows you to move backwards in the file as

well as forwards. Since less doesn't have to read the entire input file

before it starts, less starts up more quickly than text editors (for

example, vi).

You should install less because it is a basic utility for viewing text

files, and you'll use it frequently.
