Comment 4 Tomas Hoger 2014-05-26 05:00:40 EDT 
The versions of file in current Red Hat Enterprise Linux and Fedora versions, as well as versions of file included in the php packages in current Red Hat Enterprise Linux and Fedora versions, are older than 5.18 and hence are not affected by this issue.

Statement:

Not vulnerable. This issue did not affect the versions of file, php, and php53 as shipped with Red Hat Enterprise Linux 5 and 6.
