Splunk Cross-Site Scripting and Denial of Service Vulnerabilities

Two vulnerabilities have been identified in Splunk, which can be exploited by malicious people to conduct cross-site scripting attacks and cause 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.
