Bug #68745 [NEW]: Invalid HTTP requests make web server segfault

From: benjamin dot morel at gmail dot com Operating system: Fedora 21 PHP version: 5.6.4 Package: Built-in web server Bug Type: Bug Bug description:Invalid HTTP requests make web server segfault Description: ------------ I'm not sure whether this is a bug in the web server or in PHP itself, but trying to access $_SERVER when PHP has received an invalid request such as: GET www.example.com:80 HTTP/1.1 Makes the built-in web server segfault. Test script: --------------- 1. Create a test.php file containing this line: <?php print_r($_SERVER); 2. Start the built-in web server on this file: php -S localhost:8888 test.php 3. Run this PHP code to send an invalid HTTP request: $fp = fsockopen('localhost', 8888); fwrite($fp, "GET www.example.com:80 HTTP/1.1\r\n\r\n"); while (! feof($fp)) echo fread($fp, 1024); fclose($fp); The web server will segfault. -- Edit bug report at https://bugs.php.net/bug.php?id=68745&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=68745&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=68745&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=68745&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=68745&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=68745&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=68745&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=68745&r=needscript Try newer version: https://bugs.php.net/fix.php?id=68745&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=68745&r=support Expected behavior: https://bugs.php.net/fix.php?id=68745&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=68745&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=68745&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=68745&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=68745&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=68745&r=dst IIS Stability: https://bugs.php.net/fix.php?id=68745&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=68745&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=68745&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=68745&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=68745&r=mysqlcfg
