Description Andrej Nemec 2017-09-06 08:01:29 UTC
ConnMan Version 1.34 and earlier is vulnerable to a buffer overflow in the connection manager daemon (connmand) resulting in denial of service and potential remote code execution. Malformed DNS packet can result in a buffer overflow in the connection manager daemon’s DNS proxy service, resulting in service crash or remote code execution at the privilege of the service. The connection manager is not vulnerable if it is running with DNS proxy disabled (default is enabled).
