[原文]TippingPoint Intrusion Prevention System (IPS) TOS before 184.108.40.20624, and TOS 2.2.x before 220.127.116.1106, allow remote attackers to cause a denial of service (CPU consumption) via an unknown vector, probably involving an HTTP request with a negative number in the Content-Length header.
TippingPoint contains a flaw that may allow a remote denial of service. The issue is triggered when an HTTP request with a negative Content-Length is observed, and will result in loss of availability for the platform.
Upgrade to TOS version 18.104.22.16824, 22.214.171.12406 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
