"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.
