Bug #55182 [NEW]: finfo_file() doesn't detect right mime-type

From: Operating system: Ubuntu 10.04 PHP version: 5.3SVN-2011-07-11 (SVN) Package: Unknown/Other Function Bug Type: Bug Bug description:finfo_file() doesn't detect right mime-type Description: ------------ The finfo_file command detects openxml documents (xlsb, xlsx,...) as application/zip files. Can this be fixed? There are a lot of people who have to hack the mediawiki code to allow these files for upload. With these hacks they lose a part of there security: the checking of the finfo_file-mime-type against the file extension itself... Test script: --------------- php > $finfo = finfo_open(FILEINFO_MIME_TYPE); php > echo finfo_file($finfo, '/mnt/Transfert/test.xlsb'); application/zip -- Edit bug report at https://bugs.php.net/bug.php?id=55182&edit=1 -- Try a snapshot (PHP 5.2): https://bugs.php.net/fix.php?id=55182&r=trysnapshot52 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=55182&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=55182&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=55182&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=55182&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=55182&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=55182&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=55182&r=needscript Try newer version: https://bugs.php.net/fix.php?id=55182&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=55182&r=support Expected behavior: https://bugs.php.net/fix.php?id=55182&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=55182&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=55182&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=55182&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=55182&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=55182&r=dst IIS Stability: https://bugs.php.net/fix.php?id=55182&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=55182&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=55182&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=55182&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=55182&r=mysqlcfg Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=55182&r=trysnapshot54
