Description Pedro Sampaio 2017-08-21 15:19:46 EDT
A flaw was found in ConnMan 1.34 and earlier. Connman DNS-proxy feature forwards DNS queries from the localhost to an external DNS server. The DNS resonse handled from an external DNS server may cause a remote denial-of-service or possibly remote code execution if malformed. The flaw is in the lenght of the variable "name" in src/dnsproxy.c.

Upstream patch:
