Jan 28, 2017
- Cisco Content Services Gateway
Known Affected Releases
Symptom: When a HTTP stream, containing a mix of ip fragments and non fragmented packet, matches a content and policy with 'accounting type http' CSG may leak buffer, causing all traffic to get dropped by CSG. Conditions: The issue occurs only if all of the following conditions are met: 1. The data flow must match a CSG Content-Policy pair that is configured for 'accounting type http' 2. CSG sees HTTP packet which is the first packet of a transaction. 3. HTTP packet should be followed by another HTTP packet which gets ip fragment before reaching CSG. 4. Under certain timing condition CSG may leak buffer corresponding to first fragment.
