ID: 46551 Comment by: donquixote dot phplist at googlemail dot com Reported By: johnpupu at gmail dot com Status: No Feedback Bug Type: PCRE related Operating System: FreeBSD 7.0-RELEASE-p4 PHP Version: 5.2.6 New Comment:
I found a regex / text combination that causes my apache to crash / restart with preg_replace. The example is a reduced version of Drupal's CSS compression regex. The regex is not overly complex, and the text is not overly long. Reproducing this depends on system configuration: On my webspace it does not crash. But, on my localhost it makes a reproducible crash. Removing a few letters in the regexped text (no matter which) makes the bug not happen. More info in the linked file. standalone "evil script" at http://drupal.org/files/issues/test.php__1.txt (rename to *.php) posted here http://drupal.org/node/444228#comment-2089300 Previous Comments: ------------------------------------------------------------------------ [2009-09-28 05:24:19] donquixote dot phplist at googlemail dot com I found a regex / text combination that causes my apache to crash / restart with preg_replace.
