DESCRIPTION:
Filip Palian has reported two vulnerabilities in Splunk, which can be
exploited by malicious people to conduct cross-site scripting attacks
and cause a DoS (Denial of Service).

1) Input passed via the "segment" parameter to
prototype/segmentation_performance in the Splunk Web component is not
properly sanitised before being returned to the user. This can be
exploited to execute arbitrary HTML and script code in a user's
browser session in context of an affected site.

2) A boundary error within prototype/segmentation_performance in the
Splunk Web component can be exploited to exhaust system resources and
render the service inaccessible.

The vulnerabilities are reported in versions 4.0 through 4.2.3.

SOLUTION:
Update to version 4.2.4.
