CVE-2017-12616

When using a VirtualDirContext with Apache Tomcat 7.0.0 to 7.0.80 it was possible to bypass security constraints and/or view the source code of JSPs for resources served by the VirtualDirContext using a specially crafted request.

TuxCare rebuilt 32 packages to address 16 CVEs. Fixed in 7.0.70-tuxcare.4.

The CORS Filter did not add an HTTP Vary header indicating that the response varies depending on Origin. This permitted client and server side cache poisoning in some circumstances (CVE-2017-7674).
