Package : c-ares
Version : 1.9.1-3+deb7u1
CVE ID : CVE-2016-5180
Debian Bug : 839151

Gzob Qq discovered that the query-building functions in c-ares, an
asynchronous DNS request library would not correctly process crafted
query names, resulting in a heap buffer overflow and potentially
leading to arbitrary code execution.

For Debian 7 "Wheezy", these problems have been fixed in version
1.9.1-3+deb7u1.

We recommend that you upgrade your c-ares packages.
