PHP 4.0 Bug #10229 Updated: buffer error in fread

ID: 10229 User Update by: apeeters@lashout.net Old-Status: Feedback Status: Open Bug Type: Filesystem function related Description: buffer error in fread I have only seen php code once, and I was't able to reproduce it. I suppose it was a case where php code was stored in a variable (for online editing or something). This is only a guess, as it's not my code that I see, but code from someone else on the same server. Previous Comments: --------------------------------------------------------------------------- [2001-04-07 20:51:58] cnewbill@php.net I ran it through a couple hundred times and absolutely no PHP code whatsoever. The only problem I see here is $content is never cleaned up properly and contains BOTH of the fread()s jumbled. Which is very strange. $fp = fopen("http://www.newsplanet.be/", "r"); while (!feof($fp)) $content .= fread($fp, 4000); fclose($fp); You would be better off using the above as it works properly. Whomever is handling the fopen-wrappers should probably look at this. -Chris --------------------------------------------------------------------------- [2001-04-07 20:17:03] apeeters@lashout.net I've been testing a bit more and have a clear reproducible codesnippet, it yields the same results in php 4.0.4p1, so I changed the PHP version for this bugreport. ---start--- $fp = fopen("http://www.newsplanet.be/", "r"); $content = fread($fp, 100000); fclose($fp); $fp = fopen("http://www.google.com/", "r"); $content = fread($fp, 100000); mail("me@host", "topic", $content); ---stop--- In this mail, I see the sourcecode from google.com followed by the rest of the code from newsplanet.be. This does occur in about 1/3 of the mails I try, although I'm unable to see why this isn't always the case. --------------------------------------------------------------------------- [2001-04-07 19:46:47] cnewbill@php.net Can't reproduce with CVS version. Try upgrading to the newest release 4.04pl1 or grab a CVS snapshot from http://snaps.php.net/ What URL is it that is doing this? Or is it every URL? -Chris --------------------------------------------------------------------------- [2001-04-07 19:25:09] apeeters@lashout.net While running the following code, I got weird results in my mailbox. It seemed like I got the entire buffer of 100000 bytes mailed, instead of only the length of the result of the url. And those mails contained php code from another site hosted at the same server. This worries me, and I think this needs a serious checkup. The bug is reproducible :) ---start--- $fp = fopen("http://someurl/", "r"); $content = fread($fp, 100000); mail("someone@somehost", "test", $content); ---stop--- Additional info: './configure' '--prefix=/usr' '--with-apxs=/usr/sbin/apxs' '--with-gd' '--with-gettext=/usr' '--enable-safe-mode' '--with-config-file-path=/etc/httpd' '--with-exec-dir=/usr/bin' '--with-zlib' '--enable-magic-quotes' '--with-regex=system' '--with-ttf=/usr/lib/libttf.so' '--enable-track-vars' '--enable-xml' '--disable-debug' '--with-db3' '--with-interbase=shared' '--with-pgsql=shared' '--with-ldap' '--with-imap' --------------------------------------------------------------------------- Full Bug description available at: http://bugs.php.net/?id=10229
