"The remote Oracle Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the
ELSA-2023-5926 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 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)

  - 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 versions 8.0.* before 8.0.29, 8.1.* before 8.1.20, 8.2.* before 8.2.7 when using SOAP HTTP Digest
    Authentication, random value generator was not checked for failure, and was using narrower range of values
    than it should have. In case of random generator failure, it could lead to a disclosure of 31 bits of
    uninitialized memory from the client to the server, and it also made easier to a malicious server to guess
    the client's nonce. (CVE-2023-3247)

  - 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)

  - 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)

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