Debian DSA-4552-1 : php7.0 - security update

critical Nessus Plugin ID 130349
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Debian host is missing a security-related update.

Description

Emil Lerner and Andrew Danau discovered that insufficient validation in the path handling code of PHP FPM could result in the execution of arbitrary code in some setups.

Solution

Upgrade the php7.0 packages.

For the oldstable distribution (stretch), this problem has been fixed in version 7.0.33-0+deb9u6.
