Debian DLA-2397-1 : php7.0 security update

medium Nessus Plugin ID 141247

Language:

Synopsis

The remote Debian host is missing a security update.

Description

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

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.

Solution

Upgrade the affected packages.
