"Two vulnerabilities were discovered in wordpress, a web blogging tool.
The Common Vulnerabilities and Exposures project identifies the
following issues.

CVE-2016-5836

The oEmbed protocol implementation in WordPress before 4.5.3 allows
remote attackers to cause a denial of service via unspecified vectors.

CVE-2018-12895

A vulnerability was discovered in Wordpress, a web blogging tool. It
allowed remote attackers with specific roles to execute arbitrary
code.

For Debian 8 'Jessie', these problems have been fixed in version
4.1+dfsg-1+deb8u18.

We recommend that you upgrade your wordpress packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
