Affected Packages:
Security database references:
In Mitre's CVE dictionary: CVE-2018-11784.
More information:

Sergey Bobrov discovered that when the default servlet returned a redirect to a directory (e.g. redirecting to /foo/ when the user requested /foo) a specially crafted URL could be used to cause the redirect to be generated to any URI of the attackers choice.

For Debian 8 Jessie, this problem has been fixed in version 7.0.56-3+really7.0.91-1.

We recommend that you upgrade your tomcat7 packages.
