"The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare
ALMALINUX9.2:CLSA-2025:1737465408 advisory.

  - In PHP 8.0.X before 8.0.28, 8.1.X before 8.1.16 and 8.2.X before 8.2.3, password_verify() function may
    accept some invalid Blowfish hashes as valid. If such invalid hash ever ends up in the password database,
    it may lead to an application allowing any password for this entry as valid. (CVE-2023-0567)

  - In PHP versions 8.1.* before 8.1.30, 8.2.* before 8.2.24, 8.3.* before 8.3.12, HTTP_REDIRECT_STATUS
    variable is used to check whether or not CGI binary is being run by the HTTP server. However, in certain
    scenarios, the content of this variable can be controlled by the request submitter via HTTP headers, which
    can lead to cgi.force_redirect option not being correctly applied. In certain configurations this may lead
    to arbitrary file inclusion in PHP. (CVE-2024-8927)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
