php5, php7.0, php7.2 vulnerabilities
==========================================================================

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

- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in PHP.

Software Description:
- php7.2: HTML-embedded scripting language interpreter
- php7.0: HTML-embedded scripting language interpreter
- php5: HTML-embedded scripting language interpreter

Details:

It was discovered that PHP incorrectly handled restarting certain child
processes when php-fpm is used. A remote attacker could possibly use this
issue to cause a denial of service. This issue was only addressed in Ubuntu
18.04 LTS. (CVE-2015-9253)

It was discovered that PHP incorrectly handled certain exif tags in JPEG
images. A remote attacker could possibly use this issue to cause PHP to
crash, resulting in a denial of service. (CVE-2018-14851, CVE-2018-14883)
