  script_set_attribute(attribute:"description", value:
"A vulnerability was discovered in PHP, a server-side, HTML-embedded
scripting language. When PHP is processing incoming HTTP cookie
values, the cookie names are url-decoded. This may lead to cookies
with prefixes like __Host confused with cookies that decode to such
prefix, thus leading to an attacker being able to forge a cookie which
is supposed to be secure.

For Debian 9 stretch, this problem has been fixed in version
7.0.33-0+deb9u10.

We recommend that you upgrade your php7.0 packages.

For the detailed security status of php7.0 please refer to its
security tracker page at:
https://security-tracker.debian.org/tracker/php7.0

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.");
