A vulnerability in BusyBox might allow remote attackers to cause a Denial of Service condition.
|Package||sys-apps/busybox on all architectures|
|Affected versions||< 1.32.1|
|Unaffected versions||>= 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"
