"acinclude.m4, as used in the configure script in PHP 5.5.13 and
earlier, allows local users to overwrite arbitrary files via a symlink
attack on the /tmp/phpglibccheck file.

A denial of service flaw was found in the way the File Information
(fileinfo) extension parsed certain Composite Document Format (CDF)
files. A remote attacker could use this flaw to crash a PHP
application using fileinfo via a specially crafted CDF file.

A type confusion issue was found in the SPL ArrayObject and
SPLObjectStorage classes' unserialize() method. A remote attacker able
to submit specially crafted input to a PHP application, which would
then unserialize this input using one of the aforementioned methods,
could use this flaw to execute arbitrary code with the privileges of
the user running that PHP application.

Buffer overflow in the mconvert function in softmagic.c in file before
5.19, as used in the Fileinfo component in PHP before 5.4.30 and 5.5.x
before 5.5.14, allows remote attackers to cause a denial of service
(application crash) via a crafted Pascal string in a FILE_PSTRING
conversion.

A heap-based buffer overflow flaw was found in the way PHP parsed DNS
TXT records. A malicious DNS server or a man-in-the-middle attacker
could possibly use this flaw to execute arbitrary code as the PHP
interpreter if a PHP application used the dns_get_record() function to
perform a DNS query."
