Description Tomas Hoger 2015-06-17 10:57:39 EDT

PHP versions 5.4.40, 5.5.24, and 5.6.8 provide fixes for multiple PHP extensions which did not check for NULL byte in a file name or path argument for certain functions, which could lead to bypass of intended access restrictions.

Upstream fix:
http://git.php.net/?p=php-src.git;a=commitdiff;h=52b93f0cfd3cba7ff98cc5198df6ca4f23865f80

The above commit also corrects problems from the following upstream bug report:

https://bugs.php.net/bug.php?id=69353

See bug 1213407 comment 5 for more details.  It was decided to assign separate CVE ids for the issue described in the upstream bug report (CVE-2015-3411) and additional issues included in the upstream fix (CVE-2015-3412):
