Fedora 34: 2021-88ba46f2b2 Moderate: PHP Header Injection Fix

PHP is an HTML-embedded scripting language. PHP attempts to make it

easy for developers to write dynamically generated web pages. PHP also

offers built-in database integration for several commercial and

non-commercial database management systems, so writing a

database-enabled webpage with PHP is fairly simple. The most common

use of PHP coding is probably as a replacement for CGI scripts.
