USN-3953-1: PHP vulnerabilities

23 April 2019

Several security issues were fixed in PHP.



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


It was discovered that PHP incorrectly handled certain exif tags in JPEG
images. A remote attacker could use this issue to cause PHP to crash,
resulting in a denial of service, or possibly execute arbitrary code.

Update instructions

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

Ubuntu 19.04
Ubuntu 18.10
Ubuntu 18.04
Ubuntu 16.04

In Ubuntu 18.04 LTS, Ubuntu 18.10, and Ubuntu 19.04, this update uses a new
upstream release, which includes additional bug fixes.

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