USN-4166-1: PHP vulnerability

28 October 2019

PHP could be made to run programs if it received specially crafted network traffic.



  • php7.0 - HTML-embedded scripting language interpreter
  • php7.2 - HTML-embedded scripting language interpreter
  • php7.3 - HTML-embedded scripting language interpreter


It was discovered that PHP incorrectly handled certain paths when being
used in FastCGI configurations. A remote attacker could possibly use this
issue to execute arbitrary code.
