NVD Description

Note: Versions mentioned in the description apply only to the upstream jbcs-httpd24-libcurl package and not the jbcs-httpd24-libcurl package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

In libexpat in Expat before 2.2.7, XML input including XML names that contain a large number of colons could make the XML parser consume a high amount of RAM and CPU resources while processing (enough to be usable for denial-of-service attacks).
