Vulnerability Details The vulnerabilities are due to an error in the way Microsoft HIS handles UDP and TCP traffic. A remote attacker may exploit these vulnerabilities by sending a specially crafted packet to an affected server listening on UDP port 1478 or TCP ports 1477 and 1478. Successful exploitation could allow a remote attacker to cause snabase.exe, snaserver.exe, snalink.exe, or mngagent.exe to stop responding, resulting in a DoS condition. |
