Package        : ruby-mixlib-archive
CVE ID         : CVE-2017-1000026
Debian Bug     : 868572

It was discovered that ruby-mixlib-archive, a Chef Software's library
used to handle various archive formats, was vulnerable to a directory
traversal attack. This allowed attackers to overwrite arbitrary files
by using a malicious tar archive containing ".." in its entries.

For the stable distribution (stretch), this problem has been fixed in
version 0.2.0-1+deb9u1.

We recommend that you upgrade your ruby-mixlib-archive packages.
