Package : c-ares
Version : 1.9.1-3+deb7u2
CVE ID : CVE-2017-1000381
CVE-2017-1000381
The c-ares function ares_parse_naptr_reply(), which is used for
parsing NAPTR responses, could be triggered to read memory
outside of the given input buffer if the passed in DNS response
packet was crafted in a particular way.
For Debian 7 "Wheezy", these problems have been fixed in version
1.9.1-3+deb7u2.
We recommend that you upgrade your c-ares packages.
