"The remote CentOS Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the
CESA-2023:0848 advisory.

  - In PHP versions before 7.4.31, 8.0.24 and 8.1.11, the phar uncompressor code would recursively uncompress
    quines gzip files, resulting in an infinite loop. (CVE-2022-31628)

  - In PHP versions before 7.4.31, 8.0.24 and 8.1.11, the vulnerability enables network and same-site
    attackers to set a standard insecure cookie in the victim's browser which is treated as a `__Host-` or
    `__Secure-` cookie by PHP applications. (CVE-2022-31629)

  - In PHP versions prior to 7.4.33, 8.0.25 and 8.2.12, when using imageloadfont() function in gd extension,
    it is possible to supply a specially crafted font file, such as if the loaded font is used with
    imagechar() function, the read outside allocated buffer will be used. This can lead to crashes or
    disclosure of confidential information. (CVE-2022-31630)

  - A flaw was found in PHP. This issue occurs due to an uncaught integer overflow in PDO::quote() of
    PDO_SQLite returning an improperly quoted string. With the implementation of sqlite3_snprintf(), it is
    possible to force the function to return a single apostrophe if the function is called on user-supplied
    input without any length restrictions in place. (CVE-2022-31631) (CVE-2022-31631)

  - The Keccak XKCP SHA-3 reference implementation before fdc6fef has an integer overflow and resultant buffer
    overflow that allows attackers to execute arbitrary code or eliminate expected cryptographic properties.
    This occurs in the sponge function interface. (CVE-2022-37454)

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