Bug #52929 [NEW]: Segfault in filter_var with FILTER_VALIDATE_EMAIL with large amount of data

From: neufeind Operating system: PHP version: 5.3.3 Package: Unknown/Other Function Bug Type: Bug Bug description:Segfault in filter_var with FILTER_VALIDATE_EMAIL with large amount of data Description: ------------ Using the attached test-script with just a large amount of data (e.g. 8kb of just "x") segfaults php. Tried with 5.3.3 (Fedora) and also some 5.3.4-snapshot that I could get hold of. Crashed for me with around 8kb of data. If it works fine for you, maybe increase that limit to 16kb or so. Test script: --------------- <?php $email = file_get_contents('x.data'); $r = filter_var($email, FILTER_VALIDATE_EMAIL); var_dump($r); // and just dump a large number of characters like "x" in x.data // for a in seq 1 8000; do echo -n x>>x.data; done Expected result: ---------------- bool(false) Actual result: -------------- segfault -- Edit bug report at http://bugs.php.net/bug.php?id=52929&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=52929&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=52929&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=52929&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=52929&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=52929&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=52929&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=52929&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=52929&r=needscript Try newer version: http://bugs.php.net/fix.php?id=52929&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=52929&r=support Expected behavior: http://bugs.php.net/fix.php?id=52929&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=52929&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=52929&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=52929&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=52929&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=52929&r=dst IIS Stability: http://bugs.php.net/fix.php?id=52929&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=52929&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=52929&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=52929&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=52929&r=mysqlcfg
