Debian DLA-1970-1 : php5 security update

critical Nessus Plugin ID 130283
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 update.

Description

Emil Lerner, beched and d90pwn found a buffer underflow in php5-fpm, a Fast Process Manager for the PHP language, which can lead to remote code execution.

Instances are vulnerable depending on the web server configuration, in particular PATH_INFO handling. For a full list of preconditions, check: https://github.com/neex/phuip-fpizdam

For Debian 8 'Jessie', this problem has been fixed in version 5.6.40+dfsg-0+deb8u7.

We recommend that you upgrade your php5 packages.

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.
