Description    :
PHP, which stands for "PHP: Hypertext Preprocessor" is a widely-used Open
Source general-purpose scripting language that is especially suited for
Web development and can be embedded into HTML.  Its syntax draws upon C,
Java, and Perl, and is easy to learn.  The main goal of the language is to
allow web developers to write dynamically generated webpages quickly, but
you can do much more with PHP.

Vulnerabilities:

  • CGI:
    • Fixed bug GHSA-3qgc-jrrr-25jv (Bypass of CVE-2012-1823, Argument Injection in PHP-CGI). (CVE-2024-4577)
  • Filter:
    • Fixed bug GHSA-w8qr-v226-r27w (Filter bypass in filter_var FILTER_VALIDATE_URL). (CVE-2024-5458)
  • Standard:
    • Fixed bug GHSA-9fcc-425m-g385 (Bypass of CVE-2024-1874). (CVE-2024-5585)
https://nvd.nist.gov/vuln/detail/CVE-2024-4577 is 9.8 CRITICAL
https://nvd.nist.gov/vuln/detail/CVE-2024-5458 is 5.3 Medium
https://nvd.nist.gov/vuln/detail/CVE-2024-5585 is 8.8 High
I also reported it here as well: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=279979

Is there any plan on releasing an updated PHP-8.3 package? It seems PHP-8.2 has also suffered the same fate. It's stuck at 8.2.18 and missing security rated releases. I've downgraded to PHP-8.1 package, which has been kept current.
 
An update would be nice and welcome of course, but for me these have very little, read no, impact.

CVE-2024-4577 is windows specific
CVE-2024-5458 is regarding handling of urls with username+passwords, which imho is insecure anyway
CVE-2024-5585 is regarding proc_open, which maybe the more critical of the three, but personally I also consider it bad practice to run system commands from php scripts.

That said, if there is a newer PHP 8.3.x version released I'd like to be able to update it too.

Thank you for pointing this out. I just found in the older CVE (https://www.php.net/archive/2012.php#id2012-05-03-1) that Apache+mod_php and NGINX+php-fpm are not affected.
