NVD Description

Note: Versions mentioned in the description apply only to the upstream busybox package and not the busybox package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

A flaw was found in BusyBox. Incomplete path sanitization in its archive extraction utilities allows an attacker to craft malicious archives that when extracted, and under specific conditions, may write to files outside the intended directory. This can lead to arbitrary file overwrite, potentially enabling code execution through the modification of sensitive system files.
