Debian DSA-3783-1 : php5 - security update

critical Nessus Plugin ID 97068
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

Several issues have been discovered in PHP, a widely-used open source general-purpose scripting language.

- CVE-2016-10158 Loading a TIFF or JPEG malicious file can lead to a Denial-of-Service attack when the EXIF header is being parsed.

- CVE-2016-10159 Loading a malicious phar archive can cause an extensive memory allocation, leading to a Denial-of-Service attack on 32 bit computers.

- CVE-2016-10160 An attacker might remotely execute arbitrary code using a malicious phar archive. This is the consequence of an off-by-one memory corruption.

- CVE-2016-10161 An attacker with control of the unserialize() function argument can cause an out-of-bounce read. This could lead to a Denial-of-Service attack or a remote code execution.

Solution

Upgrade the php5 packages.

For the stable distribution (jessie), these problems have been fixed in version 5.6.30+dfsg-0+deb8u1.
