"An integer underflow flaw leading to out-of-bounds memory access was
found in the way PHP's Phar extension parsed Phar archives. A
specially crafted archive could cause PHP to crash or, possibly,
execute arbitrary code when opened. (CVE-2015-4021)

An integer overflow flaw leading to a heap based buffer overflow was
found in the way PHP's FTP extension parsed file listing FTP server
responses. A malicious FTP server could use this flaw to cause a PHP
application to crash or, possibly, execute arbitrary code.
(CVE-2015-4022)

A flaw was found in the way PHP parsed multipart HTTP POST requests. A
specially crafted request could cause PHP to use an excessive amount
of CPU time. (CVE-2015-4024)

It was found that certain PHP functions did not properly handle file
names containing a NULL character. A remote attacker could possibly
use this flaw to make a PHP script access unexpected files and bypass
intended file system access restrictions. (CVE-2015-4025)

It was found that certain PHP functions did not properly handle file
names containing a NULL character. A remote attacker could possibly
use this flaw to make a PHP script access unexpected files and bypass
intended file system access restrictions. (CVE-2015-4026)

PCRE library is prone to a heap overflow vulnerability. Due to
insufficient bounds checking inside compile_branch(), the heap memory
could be overflowed via a crafted regular expression. Since PCRE
library is widely used, this vulnerability should affect many
applications using it. An attacker may exploit this issue to execute
arbitrary code in the context of the user running the affected
application. (CVE-2015-2325)
