php5 vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 15.10
- Ubuntu 15.04
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS


PHP could be made to crash if it processed a specially crafted file.

Software Description:

It was discovered that the PHP phar extension incorrectly handled certain
files. A remote attacker could use this issue to cause PHP to crash,
resulting in a denial of service. (CVE-2015-7803, CVE-2015-7804)
