Package        : nginx
CVE ID         : CVE-2016-0742 CVE-2016-0746 CVE-2016-0747
Debian Bug     : 812806

Several vulnerabilities were discovered in the resolver in nginx, a
small, powerful, scalable web/proxy server, leading to denial of service
or, potentially, to arbitrary code execution. These only affect nginx if
the "resolver" directive is used in a configuration file.

For the oldstable distribution (wheezy), these problems have been fixed
in version 1.2.1-2.2+wheezy4.

For the stable distribution (jessie), these problems have been fixed in
version 1.6.2-5+deb8u1.

For the testing distribution (stretch), these problems have been fixed
in version 1.9.10-1.

For the unstable distribution (sid), these problems have been fixed in
version 1.9.10-1.

We recommend that you upgrade your nginx packages.
