Debian LTS: DLA-2614-1: busybox security update
Summary
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
