Package        : php7.0
Version        : 7.0.33-0+deb9u10
CVE ID         : CVE-2020-7070

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
