A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 16.10 - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS
Summary:
c-ares could be made to crash or run programs if it processed a specially crafted hostname.
Software Description: - c-ares: library for asynchronous name resolves
Details:
Gzob Qq discovered that c-ares incorrectly handled certain hostnames. A remote attacker could use this issue to cause applications using c-ares to crash, resulting in a denial of service, or possibly execute arbitrary code.
