{“lastseen”:””,”description”:”Multiple Cisco products are affected by a vulnerability in the processing of DCE\/RPC requests that could allow an unauthenticated, remote attacker to cause the Snort 3 Detection Engine to leak sensitive information or to restart, resulting in an interruption of packet inspection.\\r\\n\\r\\nThis vulnerability is due to an error in buffer handling logic when processing DCE\/RPC requests, which can result in a buffer out-of-bounds read. An attacker could exploit this vulnerability by sending a large number of DCE\/RPC requests through an established connection that is inspected by Snort 3. A successful exploit could allow the attacker to obtain sensitive information in the Snort 3 data
