Package        : ruby-sprockets
CVE ID         : CVE-2018-3760
Debian Bug     : 901913

Orange Tsai discovered a path traversal flaw in ruby-sprockets, a
Rack-based asset packaging system. A remote attacker can take advantage
of this flaw to read arbitrary files outside an application's root
directory via specially crafted requests, when the Sprockets server is
used in production.

For the stable distribution (stretch), this problem has been fixed in
version 3.7.0-1+deb9u1.

We recommend that you upgrade your ruby-sprockets packages.

For the detailed security status of ruby-sprockets please refer to its
security tracker page at:
https://security-tracker.debian.org/tracker/ruby-sprockets
