CWE-626  (opens in a new tab)

How to fix?

Upgrade Centos:6 php-imap to version 0:5.3.3-46.el6_6 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream php-imap package and not the php-imap package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

PHP before 5.4.42, 5.5.x before 5.5.26, and 5.6.x before 5.6.10 does not ensure that pathnames lack %00 sequences, which might allow remote attackers to read or write to arbitrary files via crafted input to an application that calls (1) a DOMDocument save method or (2) the GD imagepsloadfont function, as demonstrated by a filename\0.html attack that bypasses an intended configuration in which client users may write to only .html files.
