BusyBox: Denial of service

BusyBox: Denial of service A vulnerability in BusyBox might allow remote attackers to cause a Denial of Service condition. busybox 2021-05-26 2021-05-26 777255 local, remote 1.32.1 1.32.1

BusyBox is a set of tools for embedded systems and is a replacement for GNU Coreutils.

It was discovered that BusyBox mishandled the error bit on the huft_build result pointer when decompressing GZIP compressed data.

A remote attacker could entice a user to open a specially crafted GZIP file using BusyBox, possibly resulting in a Denial of Service condition.

There is no known workaround at this time.

All BusyBox users should upgrade to the latest version:


      # emerge --sync
      # emerge --ask --oneshot --verbose ">=sys-apps/busybox-1.32.1"
