"Updated jakarta-taglibs-standard packages that fix one security issue
are now available for Red Hat Enterprise Linux 6 and 7.

Red Hat Product Security has rated this update as having Important
security impact. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available from the
CVE link in the References section.

jakarta-taglibs-standard is the Java Standard Tag Library (JSTL). This
library is used in conjunction with Tomcat and Java Server Pages
(JSP).

It was found that the Java Standard Tag Library (JSTL) allowed the
processing of untrusted XML documents to utilize external entity
references, which could access resources on the host system and,
potentially, allowing arbitrary code execution. (CVE-2015-0254)

after applying this update. Detailed instructions on the additional
steps can be found here :

updated packages, which contain a backported patch to correct this
issue."
