Description Alexander Bergmann 2016-05-23 08:41:04 UTC 
CVE-2015-8877

The gdImageScaleTwoPass function in gd_interpolation.c in the GD Graphics
Library (aka libgd) before 2.2.0, as used in PHP before 5.6.12, uses
inconsistent allocate and free approaches, which allows remote attackers to
cause a denial of service (memory consumption) via a crafted call, as
demonstrated by a call to the PHP imagescale function.

Reproduced with 13.2 and 12:

Installed packages: php5, php5-gd

$ cat test.php
<?php
$im = imagecreatetruecolor(256, 256);
imagescale($im, 32, 32, IMG_BICUBIC);
imagedestroy($im);
?>
$

BEFORE

$ valgrind --leak-check=full php test.php
[..]
==4388== ERROR SUMMARY: 2 errors from 2 contexts (suppressed: 0 from 0)
$

AFTER

$ valgrind --leak-check=full php test.php
[..]
==13202== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 0 from 0)

Older versions are not affected.
