Description
The default GenericPortlet implementation is vulnerable to denial-of-service (DoS) attacks and information leak (CVE-2015-1926).
As a part of this fix, the JSR 286 Specification JAR (portlet.jar) has been updated to version 2.1.
Severity
Severity 1
Fixed Version(s)
Note that there are two binary patches which fix this issue, as well as all previous CST fixes for this release. You only need to apply one of these, not both.
- Binary Patch 1: The "complete" patch is a patch which merges the fixes for all reports into the original Liferay JAR files, which you can use to overwrite the existing .JAR files in your Liferay deployment. See the README file on SourceForge for more details. This patch is used in cases where classloading issues prevent proper deployment of EXT plugins, such as GlassFish.
- Binary Patch 2: The "diff" patch - this is an ordinary binary EXT-based patch (using
ext-XXXXX.jar
) like those previously issued by the CST and can be applied to most deployments. If you've successfully applied CST patches in the past, then this is the patch for you. - Source Patch: Details for working with source patches can be found on the Patching Liferay Portal page.
