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.
