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

Edit report at http://bugs.php.net/bug.php?id=52929&edit=1 ID: 52929 Comment by: neufeind@php.net Reported by: neufeind@php.net Summary: Segfault in filter_var with FILTER_VALIDATE_EMAIL with large amount of data Status: Open Type: Bug Package: Unknown/Other Function PHP Version: 5.3.3 Block user comment: N New Comment: Looking at the source at http://svn.php.net/viewvc/php/php-src/trunk/ext/filter/logical_filters.c?view=markup I wonder if the problem itself might be in the pcre-lib used since the email-validation itself is PCRE-based? Fedora Linux here ships with PCRE 7.8.

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 this bug report at http://bugs.php.net/bug.php?id=52929&edit=1
