Debian DSA-4403-1 : php7.0 - security update

critical Nessus Plugin ID 122722
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

Multiple security issues were found in PHP, a widely-used open source general purpose scripting language: The EXIF extension had multiple cases of invalid memory access and rename() was implemented insecurely.

Solution

Upgrade the php7.0 packages.

For the stable distribution (stretch), this problem has been fixed in version 7.0.33-0+deb9u3.
