therefore, affected by an out-of-bounds read error in its url decoding component due to insufficient validation of 
user-supplied input. An unauthenticated, remote attacker can exploit this, by sending specially crafted requests, to 
cause a denial of service (DoS) condition or execution of arbitrary code.

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

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-2020-7066 An URL containing zero (\0) character will be truncated

possibly send some information to a wrong server.

CVE-2020-7067 Using a malformed url-encoded string an Out-of-Bounds

For Debian 8 'Jessie', these problems have been fixed in version
5.6.40+dfsg-0+deb8u11.
