The DNS domain name record decompression functionality does not properly validate the pointer offset values. The parsing of malformed responses could result in a read access past the end of an allocated structure. An attacker with a privileged position in the network could leverage this vulnerability to cause a denial-of-service condition. SIMOTICS CONNECT 400 is a connector and sensor box installed on a low-voltage motor and provides analysis data for the MindSphere application SIDRIVE IQ Fleet. \n\r\n\r\nSiemens SIMOTICS CONNECT 400 has a denial of service vulnerability.
