Patches addressing busybox security flaws in Ubuntu 20.04, 22.04, and 24.04 enhance overall system protection.
Several security issues were fixed in BusyBox.

Summary

Several security issues were fixed in BusyBox.

Software Description:

- busybox: Tiny utilities for small and embedded systems

Details:

It was discovered that BusyBox did not properly validate user input when

performing certain arithmetic operations. If a user or automated system

were tricked into processing a specially crafted file, an attacker could

possibly use this issue to cause a denial of service, or execute arbitrary

code. (CVE-2022-48174)

It was discovered that BusyBox incorrectly managed memory when evaluating

certain awk expressions. An attacker could possibly use this issue to cause

a denial of service, or execute arbitrary code. This issue only affected

Ubuntu 24.04 LTS. (CVE-2023-42363, CVE-2023-42364, CVE-2023-42365)
