[php-maint] Bug#759561: php5-common: PHP 5.4.4-14+deb7u14: finfo_buffer generates out of memory error on sample file

[flod]

Package: php5-common
Version: 5.4.4-14+deb7u14
Severity: normal

Dear Maintainer,

Starting after last update, this simple code generates an out of memory error

	$filename = 'test.lang';
	$filecontent = file_get_contents($filename);
	$info = finfo_open(FILEINFO_MIME_ENCODING);
	$type = finfo_buffer($info, $filecontent);
	finfo_close($info);
	print "{$type} - {$filename}";

PHP Fatal error:  Out of memory (allocated 524288) (tried to allocate 4294965546 bytes) 
in /home/user/test.php on line 6

Sample file to read: https://www.dropbox.com/s/ii8ybpk8bvxw1rz/test.lang?dl=0

Not sure how useful it is, but if I remove line 352 the error disappears.
If I put only that line in one file I don't get any error.

Same code has been working fine with this file for several months.
