[SECURITY] [DLA 1739-1] rails security update



-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512

Package        : rails
Version        : 2:4.1.8-1+deb8u5
CVE ID         : CVE-2019-5418 CVE-2019-5419
Debian Bug     : 924520

John Hawthorn of Github discovered a file content disclosure
vulnerability in Rails, a ruby based web application framework.
Specially crafted accept headers in combination with calls to `render
file:` can cause arbitrary files on the target server to be rendered,
disclosing the file contents.

This vulnerability could also be exploited for a denial-of-service
attack.

For Debian 8 "Jessie", these problems have been fixed in version
2:4.1.8-1+deb8u5.

We recommend that you upgrade your rails packages.
