Description
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. Security Fix(es): * php: PHP OpenSSL extension: Denial of Service due to buffer allocation flaw in AES-WRAP-PAD (CVE-2026-14355) Bug Fix(es) and Enhancement(s): * Rebase PHP to 8.4.23 for CVE-2026-14355 in 10.2.z (JIRA:RHEL-192616) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
