CVE-2003-1132
Cisco Content Services Switch 11000 and 11500 - Denial of Service via AAAA Record Handling
Title source: llmDescription
The DNS server for Cisco Content Service Switch (CSS) 11000 and 11500, when prompted for a nonexistent AAAA record, responds with response code 3 (NXDOMAIN or "Name Error") instead of response code 0 ("No Error"), which allows remote attackers to cause a denial of service (inaccessible domain) by forcing other DNS servers to send and cache a request for a AAAA record to the vulnerable server.
