The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6305-2 advisory.

  - In PHP versions 8.0.* before 8.0.30, 8.1.* before 8.1.22, and 8.2.* before 8.2.8 various XML functions     rely on libxml global state to track configuration variables, like whether external entities are loaded.
    This state is assumed to be unchanged unless the user explicitly changes it by calling appropriate     function. However, since the state is process-global, other modules - such as ImageMagick - may also use     this library within the same process, and change that global state for their internal purposes, and leave     it in a state where external entities loading is enabled. This can lead to the situation where external     XML is parsed with external entities loaded, which can lead to disclosure of any local files accessible to     PHP. This vulnerable state may persist in the same process across many requests, until the process is shut     down. (CVE-2023-3823)

  - In PHP version 8.0.* before 8.0.30, 8.1.* before 8.1.22, and 8.2.* before 8.2.8, when loading phar file,     while reading PHAR directory entries, insufficient length checking may lead to a stack buffer overflow,     leading potentially to memory corruption or RCE. (CVE-2023-3824)

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