USN-3766-1: PHP vulnerabilities

18 September 2018

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)
