"It was found that the security update of busybox announced as
DLA-1445-1 to prevent the exploitation of CVE-2011-5325, a symlinking
attack, was too strict in case of cpio archives. This update restores
the old behavior.

For Debian 8 'Jessie', this problem has been fixed in version
1:1.22.0-9+deb8u4.

We recommend that you upgrade your busybox packages.

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."
