Summary
Important: php8.4 security, bug fix, and enhancement update
Details

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: ext-pgsql: PHP: SQL injection via improper backslash escaping (CVE-2026-17543)
  • php: PHP: Arbitrary code execution via out-of-bounds write in bccomp() (CVE-2026-17544)

Bug Fix(es) and Enhancement(s):

  • Rebase PHP to 8.4.24 for CVE-2026-17543 and CVE-2026-7260 and CVE-2026-17544 in 10.2.z (JIRA:AlmaLinux-223949)
