"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.

gd_ctx.c in the GD component in PHP 5.4.x before 5.4.32 and 5.5.x
before 5.5.16 does not ensure that pathnames lack %00 sequences, which
might allow remote attackers to overwrite arbitrary files via crafted
input to an application that calls the (1) imagegd, (2) imagegd2, (3)
imagegif, (4) imagejpeg, (5) imagepng, (6) imagewbmp, or (7) imagewebp
function.

The gdImageCreateFromXpm function in gdxpm.c in libgd, as used in PHP
5.4.26 and earlier, allows remote attackers to cause a denial of
service (NULL pointer dereference and application crash) via a crafted
color table in an XPM file.

Integer overflow in the cdf_read_property_info function in cdf.c in
file through 5.19, as used in the Fileinfo component in PHP before
5.4.32 and 5.5.x before 5.5.16, allows remote attackers to cause a
denial of service (application crash) via a crafted CDF file. NOTE:
this vulnerability exists because of an incomplete fix for
CVE-2012-1571 ."
