1st part of the reproducer allow to raise a segfault uploading a specially crafted data file, when a web app call fileinfo() for this file.

It affects php >= 5.4.15 (with file 5.14).

2nd part of the reproducer allow to raise a segfault but with a specially crafted magic file. So is not remotely exploitable.

It affects php >= 5.3.0 (with file >= 5.03)

Plan is to apply the proposed patch in 5.4 + 5.5 and to update to new upstream libmagic from file 5.17 (which includes the fix).
