  script_tag(name:"insight", 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: [link moved to references]

Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: [link moved to references]");
