CVE-2017-7674

The CORS Filter in Apache Tomcat 9.0.0.M1 to 9.0.0.M21, 8.5.0 to 8.5.15, 8.0.0.RC1 to 8.0.44 and 7.0.41 to 7.0.78 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.

TuxCare rebuilt 7 packages to address 11 CVEs. Fixed in 7.0.70-tuxcare.3.

TuxCare rebuilt 5 packages to address 4 CVEs. Fixed in 7.0.109-tuxcare.5.

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).

When using a VirtualDirContext 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 (CVE-2017-12616).

Note that CVE-2017-12616 only affected tomcat 7 in Mageia 5.

This update for tomcat fixes the following issues:

It was discovered that Tomcat incorrectly handled certain pipelined requests when sendfile was used. A remote attacker could use this issue to obtain wrong responses possibly containing sensitive information. (CVE-2017-5647)

It was discovered that Tomcat incorrectly used the appropriate facade object. A malicious application could possibly use this to bypass Security Manager restrictions. (CVE-2017-5648)

It was discovered that Tomcat incorrectly handled error pages. A remote attacker could possibly use this issue to replace or remove the custom error page. (CVE-2017-5664)

It was discovered that Tomcat incorrectly handled the CORS filter. A remote attacker could possibly use this issue to perform cache poisoning. (CVE-2017-7674)
