CVE-2017-12865 connman: Stack-based buffer overflow in parse_response function in src/dnsproxy.c
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.

## Abstract
This paper presents , a software diversity-based framework designed to resist ROP attacks on Linux-based IoT devices. generates unique, semantically equivalent but syntactically different rewrites of IoT firmware, disrupting large-scale replication of ROP attacks. employs STOKE, a stochastic optimizer for x86 binaries, as its core diversity engine but introduces significant extensions to address unique IoT firmware challenges.
's effectiveness is evaluated using , a published botnet DDoS attack simulation testbed.
Results demonstrate that successfully neutralizes ROP payloads by diversifying critical basic blocks i
