USN-3566-1: PHP vulnerabilities

12 February 2018

Several security issues were fixed in PHP.



  • php5 - HTML-embedded scripting language interpreter


It was discovered that PHP incorrectly handled the PHAR 404 error page. A
remote attacker could possibly use this issue to conduct cross-site
scripting (XSS) attacks. (CVE-2018-5712)

It was discovered that PHP incorrectly handled memory when unserializing
certain data. A remote attacker could use this issue to cause PHP to crash,
resulting in a denial of service, or possibly execute arbitrary code.

It was discovered that PHP incorrectly handled 'front of' and 'back of'
date directives. A remote attacker could possibly use this issue to obtain
sensitive information. (CVE-2017-16642)

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 14.04

In general, a standard system update will make all the necessary changes.
