From: peter dot mescalchin at gmail dot com Operating system: Windows XP PHP version: 5.1.5 PHP Bug Type: PCRE related Bug description: PCRE 6.6 crashing PHP with specific calls to preg_match()
Description: ------------ Passing large strings to PCRE functions in PHP versions 5.1.3 or greater and Apache 2.0.59 with the regexp "/(\r|\n|.)*/" crashes PHP/Apache request. Referring to the source code, a string length greater than 376 character crashes the request. Rolling back to PHP 5.1.2, using PCRE 6.2 works correctly without crashing for string lengths greater than 376 characters. The bug is very similar to the following PHP bug report: http://bugs.php.net/bug.php?id=24460 Reproduce code: --------------- <?PHP $test = str_repeat('a',377); // preg_match() will crash the request preg_match('/(\r|\n|.)*/',$test); ?> Expected result: ---------------- The script to end gracefully. Actual result: -------------- Crashing of the PHP request. -- Edit bug report at http://bugs.php.net/?id=38512&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=38512&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=38512&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=38512&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=38512&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=38512&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=38512&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=38512&r=needscript Try newer version: http://bugs.php.net/fix.php?id=38512&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=38512&r=support Expected behavior: http://bugs.php.net/fix.php?id=38512&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=38512&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=38512&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=38512&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=38512&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=38512&r=dst IIS Stability: http://bugs.php.net/fix.php?id=38512&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=38512&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=38512&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=38512&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=38512&r=mysqlcfg
