"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)

In PHP versions 7.3.x below 7.3.13 and 7.4.0 on Windows, when
supplying custom headers to mail() function, due to mistake introduced
in commit 78f4b4a2dcf92ddbccea1bb95f8390a18ac3342e, if the header is
supplied in lowercase, this can result in double-freeing certain
memory locations. (CVE-2019-11049)

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)

A flaw was discovered in the link function in PHP. When compiled on
Windows, it does not correctly handle paths containing NULL bytes. An
attacker could abuse this flaw to bypass application checks on file
paths. (CVE-2019-11044)

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-2019-11050)

In PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0, PHP
bcmath extension functions on some systems, including Windows, can be
tricked into reading beyond the allocated space by supplying it with
string containing characters that are identified as numeric by the OS
but aren't ASCII numbers. This can read to disclosure of the content
of some memory locations. (CVE-2019-11046)"

    \0 byte character and treats them as terminating at that byte. 
    An attacker can exploit this to disclose information in 
    applications checking paths that the code is allowed to access.

  - An out-of-bounds READ error exists in the bcmath extension due to
    an input validation error. An unauthenticated, remote attacker 
    can exploit this by supplying a string containing characters that
    are identified as numeric by the OS but are not ASCII number. 
    This can cause lead to the disclosure of information within some
    memory locations. (CVE-2019-11046)

  - An out-of-bounds READ error exists in parsing EXIF information
