The remote Ubuntu 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5300-1 advisory.

  - An issue was discovered in PHP 7.3.x before 7.3.0alpha3, 7.2.x before 7.2.8, and before 7.1.20. The php-     fpm master process restarts a child process in an endless loop when using program execution functions     (e.g., passthru, exec, shell_exec, or system) with a non-blocking STDIN stream, causing this master     process to consume 100% of the CPU, and consume disk space with a large volume of error logs, as     demonstrated by an attack by a customer of a shared-hosting facility. (CVE-2015-9253)

  - The zend_string_extend function in Zend/zend_string.h in PHP through 7.1.5 does not prevent changes to     string objects that result in a negative length, which allows remote attackers to cause a denial of     service (application crash) or possibly have unspecified other impact by leveraging a script's use of .=     with a long string. (CVE-2017-8923)

  - PHP 7.1.5 has an Out of bounds access in php_pcre_replace_impl via a crafted preg_replace call.
    (CVE-2017-9118)

  - The i_zval_ptr_dtor function in Zend/zend_variables.h in PHP 7.1.5 allows attackers to cause a denial of     service (memory consumption and application crash) or possibly have unspecified other impact by triggering     crafted operations on array data structures. (CVE-2017-9119)

  - PHP 7.x through 7.1.5 allows remote attackers to cause a denial of service (buffer overflow and     application crash) or possibly have unspecified other impact via a long string because of an Integer     overflow in mysqli_real_escape_string. (CVE-2017-9120)

  - In PHP versions 7.3.x below 7.3.33, 7.4.x below 7.4.26 and 8.0.x below 8.0.13, certain XML parsing     functions, like simplexml_load_file(), URL-decode the filename passed to them. If that filename contains     URL-encoded NUL character, this may cause the function to interpret this as the end of the filename, thus     interpreting the filename differently from what the user intended, which may lead it to reading a     different file than intended. (CVE-2021-21707)

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

    phar_tar_writeheaders_int in ext/phar/tar.c has a buffer overflow via a long link value. NOTE: The vendor     indicates that the link value is used only when an archive contains a symlink, which currently cannot     happen: This issue allows theoretical compromise of security, but a practical attack is usually     impossible. (CVE-2019-9675)

  - When using fgetss() function to read data with stripping tags, in PHP versions 7.2.x below 7.2.27, 7.3.x     below 7.3.14 and 7.4.x below 7.4.2 it is possible to supply data that will cause this function to read     past the allocated buffer. This may lead to information disclosure or crash. (CVE-2020-7059)

  - When using certain mbstring functions to convert multibyte encodings, in PHP versions 7.2.x below 7.2.27,     7.3.x below 7.3.14 and 7.4.x below 7.4.2 it is possible to supply data that will cause function     mbfl_filt_conv_big5_wchar to read past the allocated buffer. This may lead to information disclosure or     crash. (CVE-2020-7060)

  - In PHP versions 7.2.x below 7.2.28, 7.3.x below 7.3.15 and 7.4.x below 7.4.3, when using file upload     functionality, if upload progress tracking is enabled, but session.upload_progress.cleanup is set to 0     (disabled), and the file upload fails, the upload procedure would try to clean up data that does not exist     and encounter null pointer dereference, which would likely lead to a crash. (CVE-2020-7062)

  - In PHP versions 7.2.x below 7.2.28, 7.3.x below 7.3.15 and 7.4.x below 7.4.3, when creating PHAR archive     using PharData::buildFromIterator() function, the files are added with default permissions (0666, or all     access) even if the original files on the filesystem were with more restrictive permissions. This may     result in files having more lax permissions than intended when such archive is extracted. (CVE-2020-7063)

  - In PHP versions 7.2.x below 7.2.9, 7.3.x below 7.3.16 and 7.4.x below 7.4.4, while parsing EXIF data with     exif_read_data() function, it is possible for malicious data to cause PHP to read one byte of     uninitialized memory. This could potentially lead to information disclosure or crash. (CVE-2020-7064)

  - In PHP versions 7.2.x below 7.2.29, 7.3.x below 7.3.16 and 7.4.x below 7.4.4, while using get_headers()     with user-supplied URL, if the URL contains zero (\0) character, the URL will be silently truncated at it.
    This may cause some software to make incorrect assumptions about the target of the get_headers() and     possibly send some information to a wrong server. (CVE-2020-7066)

  - In PHP versions 7.2.x below 7.2.33, 7.3.x below 7.3.21 and 7.4.x below 7.4.9, while processing PHAR files     using phar extension, phar_parse_zipfile could be tricked into accessing freed memory, which could lead to     a crash or information disclosure. (CVE-2020-7068)

  - In PHP versions 7.2.x below 7.2.34, 7.3.x below 7.3.23 and 7.4.x below 7.4.11, when AES-CCM mode is used     with openssl_encrypt() function with 12 bytes IV, only first 7 bytes of the IV is actually used. This can     lead to both decreased security and incorrect encryption data. (CVE-2020-7069)

  - In PHP versions 7.2.x below 7.2.34, 7.3.x below 7.3.23 and 7.4.x below 7.4.11, when PHP is processing     incoming HTTP cookie values, the cookie names are url-decoded. This may lead to cookies with prefixes like
    __Host confused with cookies that decode to such prefix, thus leading to an attacker being able to forge     cookie which is supposed to be secure. See also CVE-2020-8184 for more information. (CVE-2020-7070)

  - In PHP versions 7.3.x below 7.3.26, 7.4.x below 7.4.14 and 8.0.0, when validating URL with functions like     filter_var($url, FILTER_VALIDATE_URL), PHP will accept an URL with invalid password as valid URL. This may     lead to functions that rely on URL being valid to mis-parse the URL and produce wrong data as components     of the URL. (CVE-2020-7071)

  - In PHP versions 7.3.x below 7.3.27, 7.4.x below 7.4.15 and 8.0.x below 8.0.2, when using SOAP extension to     connect to a SOAP server, a malicious SOAP server could return malformed XML data as a response that would     cause PHP to access a null pointer and thus cause a crash. (CVE-2021-21702)

  - In PHP versions 7.3.x up to and including 7.3.31, 7.4.x below 7.4.25 and 8.0.x below 8.0.12, when running     PHP FPM SAPI with main FPM daemon process running as root and child worker processes running as lower-     privileged users, it is possible for the child processes to access memory shared with the main process and     write to it, modifying it in a way that would cause the root process to conduct invalid memory reads and     writes, which can be used to escalate privileges from local unprivileged user to the root user.
    (CVE-2021-21703)

  - In PHP versions 7.3.x below 7.3.29, 7.4.x below 7.4.21 and 8.0.x below 8.0.8, when using Firebird PDO     driver extension, a malicious database server could cause crashes in various database functions, such as     getAttribute(), execute(), fetch() and others by returning invalid response data that is not parsed     correctly by the driver. This can result in crashes, denial of service or potentially memory corruption.
    (CVE-2021-21704)

  - In PHP versions 7.3.x below 7.3.29, 7.4.x below 7.4.21 and 8.0.x below 8.0.8, when using URL validation     functionality via filter_var() function with FILTER_VALIDATE_URL parameter, an URL with invalid password     field can be accepted as valid. This can lead to the code incorrectly parsing the URL and potentially     leading to other security implications - like contacting a wrong server or making a wrong access decision.
    (CVE-2021-21705)

  - In PHP versions 7.3.x below 7.3.33, 7.4.x below 7.4.26 and 8.0.x below 8.0.13, certain XML parsing     functions, like simplexml_load_file(), URL-decode the filename passed to them. If that filename contains     URL-encoded NUL character, this may cause the function to interpret this as the end of the filename, thus     interpreting the filename differently from what the user intended, which may lead it to reading a     different file than intended. (CVE-2021-21707)

  - In PHP versions 7.4.x below 7.4.30, 8.0.x below 8.0.20, and 8.1.x below 8.1.7, when using Postgres     database extension, supplying invalid parameters to the parametrized query may lead to PHP attempting to     free memory using uninitialized data as pointers. This could lead to RCE vulnerability or denial of     service. (CVE-2022-31625)

  - In PHP versions 7.4.x below 7.4.30, 8.0.x below 8.0.20, and 8.1.x below 8.1.7, when pdo_mysql extension     with mysqlnd driver, if the third party is allowed to supply host to connect to and the password for the     connection, password of excessive length can trigger a buffer overflow in PHP, which can lead to a remote     code execution vulnerability. (CVE-2022-31626)

  - 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)

  - 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)
