Debian DLA-2614-1 : busybox security update

high Nessus Plugin ID 148302

Language:

Synopsis

The remote Debian host is missing a security update.

Description

The gunzip decompressor of Busybox, tiny utilities for small and embedded systems, mishandled the error bit on the huft_build result pointer, with a resultant invalid free or segmentation fault, via malformed gzip data.

For Debian 9 stretch, this problem has been fixed in version 1:1.22.0-19+deb9u2.

We recommend that you upgrade your busybox packages.

For the detailed security status of busybox please refer to its security tracker page at:

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
