"The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the
dsa-5363 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, core path resolution function
    allocate buffer one byte too small. When resolving paths with lengths close to system MAXPATHLEN setting,
    this may lead to the byte after the allocated buffer being overwritten with NUL value, which might lead to
    unauthorized data access or modification. (CVE-2023-0568)

  - In PHP 8.0.X before 8.0.28, 8.1.X before 8.1.16 and 8.2.X before 8.2.3, excessive number of parts in HTTP
    form upload can cause high resource consumption and excessive number of log entries. This can cause denial
    of service on the affected server by exhausting CPU resources or disk space. (CVE-2023-0662)

  - php: PDO::quote() may return unquoted string due to an integer overflow (CVE-2022-31631)

  - Password_verify() always return true with some hash [fedora-36] (CVE-2023-0567)

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