CVE-2017-12865: Buffer Overflow
First published: Mon Aug 21 2017(Updated: )
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: <a href="https://git.kernel.org/pub/scm/network/connman/connman.git/commit/?id=5c281d182ecdd0a424b64f7698f32467f8f67b71">https://git.kernel.org/pub/scm/network/connman/connman.git/commit/?id=5c281d182ecdd0a424b64f7698f32467f8f67b71</a>
