Bug #69551 [NEW]: parse_ini_file() and parse_ini_string() segmentation fault

From: nystrom dot lars dot egon at gmail dot com Operating system: Linux PHP version: 5.6.8 Package: Filesystem function related Bug Type: Bug Bug description:parse_ini_file() and parse_ini_string() segmentation fault Description: ------------ This bug affects both parse_ini_file() and parse_ini_string(). If you try to parse a string which contains a line feed followed by an escape character PHP will crash with a segmentation fault. This only happens when using the INI_SCANNER_RAW mode. With "line feed followed by escape character" I mean two bytes with the following values: 0x0A 0x1B. This affects all version of PHP I've tried: PHP 5.6.8, PHP 5.5.24 and PHP 5.3.29. Test script: --------------- <?php $a = '[Network.eth0] SubnetMask = " "'; parse_ini_string($a, false, \INI_SCANNER_RAW); -- Edit bug report at https://bugs.php.net/bug.php?id=69551&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=69551&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=69551&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=69551&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=69551&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=69551&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=69551&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=69551&r=needscript Try newer version: https://bugs.php.net/fix.php?id=69551&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=69551&r=support Expected behavior: https://bugs.php.net/fix.php?id=69551&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=69551&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=69551&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=69551&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=69551&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=69551&r=dst IIS Stability: https://bugs.php.net/fix.php?id=69551&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=69551&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=69551&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=69551&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=69551&r=mysqlcfg
