USN-3766-1: PHP vulnerabilities

18 September 2018

Several security issues were fixed in PHP.



  • php5 - HTML-embedded scripting language interpreter
  • php7.0 - HTML-embedded scripting language interpreter
  • php7.2 - HTML-embedded scripting language interpreter


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)

Update instructions

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

Ubuntu 18.04
Ubuntu 16.04
Ubuntu 14.04

In Ubuntu 16.04 LTS and Ubuntu 18.04 LTS, this update uses a new upstream
release, which includes additional bug fixes.

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