What is CVE-2017-12865?

A stack-based buffer overflow vulnerability exists in ConnMan versions 1.34 and earlier. This flaw arises in the 'dnsproxy.c' file, where remote attackers can exploit a crafted response query string directed at the 'name' variable. Successful exploitation could lead to a denial of service condition or enable attackers to execute arbitrary code on affected systems. This vulnerability underscores the importance of secure coding practices and timely patching to mitigate risks in IoT devices and Linux systems.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
