Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The version of php73 installed on the remote host is prior to 7.3.17-1.25. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2020-1368 advisory.

    In PHP versions 7.2.x below 7.2.9, 7.3.x below 7.3.16 and 7.4.x below 7.4.34, 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 7.3.x below 7.3.16 and 7.4.x below 7.4.34, while using mb_strtolower() function with     UTF-32LE encoding, certain invalid strings could cause PHP to overwrite stack-allocated buffer. This could     lead to memory corruption, crashes and potentially code execution. (CVE-2020-7065)

    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 7.2.30, 7.3.x below 7.3.17 and 7.4.x below 7.4.5, if PHP is compiled with     EBCDIC support (uncommon), urldecode() function can be made to access locations past the allocated memory,     due to erroneously using signed numbers as array indexes. (CVE-2020-7067)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

The remote host is affected by the vulnerability described in GLSA-202003-57 (PHP: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in PHP. Please review the       CVE identifiers referenced below for details.
  Impact :

    An attacker could possibly execute arbitrary shell commands, cause a       Denial of Service condition or obtain sensitive information.
  Workaround :

    There is no known workaround at this time.

The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2020:3662 advisory.

  - Function iconv_mime_decode_headers() in PHP versions 7.1.x below 7.1.30, 7.2.x below 7.2.19 and 7.3.x     below 7.3.6 may perform out-of-buffer read due to integer overflow when parsing MIME headers. This may     lead to information disclosure or crash. (CVE-2019-11039)

  - When PHP EXIF extension is parsing EXIF information from an image, e.g. via exif_read_data() function, in     PHP versions 7.1.x below 7.1.30, 7.2.x below 7.2.19 and 7.3.x below 7.3.6 it is possible to supply it with     data what will cause it to read past the allocated buffer. This may lead to information disclosure or     crash. (CVE-2019-11040)

  - When PHP EXIF extension is parsing EXIF information from an image, e.g. via exif_read_data() function, in     PHP versions 7.1.x below 7.1.31, 7.2.x below 7.2.21 and 7.3.x below 7.3.8 it is possible to supply it with     data what will cause it to read past the allocated buffer. This may lead to information disclosure or     crash. (CVE-2019-11041, CVE-2019-11042)

  - In PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0, PHP DirectoryIterator class accepts     filenames with embedded \0 byte and treats them as terminating at that byte. This could lead to security     vulnerabilities, e.g. in applications checking paths that the code is allowed to access. (CVE-2019-11045)

  - When PHP EXIF extension is parsing EXIF information from an image, e.g. via exif_read_data() function, in     PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0 it is possible to supply it with data what     will cause it to read past the allocated buffer. This may lead to information disclosure or crash.
    (CVE-2019-11047, CVE-2019-11050)

  - In PHP versions 7.2.x below 7.2.31, 7.3.x below 7.3.18 and 7.4.x below 7.4.6, when HTTP file uploads are     allowed, supplying overly long filenames or field names could lead PHP engine to try to allocate oversized     memory storage, hit the memory limit and stop processing the request, without cleaning up temporary files     created by upload request. This potentially could lead to accumulation of uncleaned temporary files     exhausting the disk space on the target server. (CVE-2019-11048)

  - A use-after-free in onig_new_deluxe() in regext.c in Oniguruma 6.9.2 allows attackers to potentially cause     information disclosure, denial of service, or possibly code execution by providing a crafted regular     expression. The attacker provides a pair of a regex pattern and a string, with a multi-byte encoding that     gets handled by onig_new_deluxe(). Oniguruma issues often affect Ruby, as well as common optional     libraries for PHP and Rust. (CVE-2019-13224)

  - A NULL Pointer Dereference in match_at() in regexec.c in Oniguruma 6.9.2 allows attackers to potentially     cause denial of service by providing a crafted regular expression. Oniguruma issues often affect Ruby, as     well as common optional libraries for PHP and Rust. (CVE-2019-13225)

  - Oniguruma before 6.9.3 allows Stack Exhaustion in regcomp.c because of recursion in regparse.c.
    (CVE-2019-16163)

  - An issue was discovered in Oniguruma 6.x before 6.9.4_rc2. In the function gb18030_mbc_enc_len in file     gb18030.c, a UChar pointer is dereferenced without checking if it passed the end of the matched string.
    This leads to a heap-based buffer over-read. (CVE-2019-19203)

  - An issue was discovered in Oniguruma 6.x before 6.9.4_rc2. In the function fetch_interval_quantifier     (formerly known as fetch_range_quantifier) in regparse.c, PFETCH is called without checking PEND. This     leads to a heap-based buffer over-read. (CVE-2019-19204)

  - Oniguruma through 6.9.3, as used in PHP 7.3.x and other products, has a heap-based buffer over-read in     str_lower_case_match in regexec.c. (CVE-2019-19246)

  - An out-of-bounds read was discovered in PCRE before 10.34 when the pattern \X is JIT compiled and used to     match specially crafted subjects in non-UTF mode. Applications that use PCRE to parse untrusted input may     be vulnerable to this flaw, which would allow an attacker to crash the application. The flaw occurs in     do_extuni_no_utf in pcre2_jit_compile.c. (CVE-2019-20454)

  - 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 7.3.x below 7.3.16 and 7.4.x below 7.4.4, while using mb_strtolower() function with     UTF-32LE encoding, certain invalid strings could cause PHP to overwrite stack-allocated buffer. This could     lead to memory corruption, crashes and potentially code execution. (CVE-2020-7065)

  - 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)
