Debian DSA-4353-1 : php7.0 - security update

high Nessus Plugin ID 119561
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 module was susceptible to denial of service/information disclosure when parsing malformed images, the Apache module allowed cross-site-scripting via the body of a 'Transfer-Encoding: chunked' request and the IMAP extension performed insufficient input validation which can result in the execution of arbitrary shell commands in the imap_open() function and denial of service in the imap_mail() function.

Solution

Upgrade the php7.0 packages.

For the stable distribution (stretch), these problems have been fixed in version 7.0.33-0+deb9u1.
