From: remijnj at eidetica dot com Operating system: Linux (Slackware 9.1) PHP version: 4.3.5RC3 PHP Bug Type: HTTP related Bug description: uninitialized memory in http_fopen_wrapper.c error handling
Description: ------------ I have seen uninitialized memory being printed out in my php eror log. Some of the errors are like: [24-Feb-2004 12:00:12] PHP Warning: file_get_contents(<snip>) failed to open stream: HTTP request failed! ??B^P in /usr/local/www/include/file.inc on line 17 This happened when the apache server i connected to was too busy to handle the request (load way too high). In that specific case tmp_line will be used uninitialized. This code could possibly lead to a SEGV (Segmentation Violation). Looking at the code i also spotted another (more unlikely) bug which could also result in a SEGV. I have prepared a patch against 4.3.5RC5 which should solve this problem (in my opinion). If anyone has any questions on this report or my patch (which i will try to add later) please contact me. -- Edit bug report at http://bugs.php.net/?id=27383&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=27383&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=27383&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=27383&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=27383&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=27383&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=27383&r=needscript Try newer version: http://bugs.php.net/fix.php?id=27383&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=27383&r=support Expected behavior: http://bugs.php.net/fix.php?id=27383&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=27383&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=27383&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=27383&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=27383&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=27383&r=dst IIS Stability: http://bugs.php.net/fix.php?id=27383&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=27383&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=27383&r=float
