ID: 22437 Updated by: iliaa@php.net Reported By: olle at compound dot se Status: Feedback Bug Type: ODBC related Operating System: Redhat7.2/kernel 2.4.9 PHP Version: 4.3.1 Assigned To: kalowsky New Comment: Please try using this CVS snapshot: http://snaps.php.net/php4-STABLE-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-STABLE-latest.zip Previous Comments: ------------------------------------------------------------------------ [2003-02-26 15:32:16] iliaa@php.net Try applying the patch at (againt latest stable CVS): http://bb.prohost.org/odbc43.txt If the problem is the result of sprintf() overflow this should correct it. ------------------------------------------------------------------------ [2003-02-26 09:59:02] mboeren@php.net From php_odbc.c: void odbc_do_connect(INTERNAL_FUNCTION_PARAMETERS, int persistent) ... len = strlen(db) + strlen(uid) + strlen(pwd) + sizeof(ODBC_TYPE) + 5; hashed_details = emalloc(len); hashed_len = sprintf(hashed_details, "%s_%s_%s_%s_%d", ODBC_TYPE, db, uid, pwd, cur_opt); ==> shouldn't len include the length of the string representation of cur_opt? Hope this helps, Marc. ------------------------------------------------------------------------ [2003-02-26 09:48:57] sniper@php.net don't change the status.. ------------------------------------------------------------------------ [2003-02-26 09:44:13] olle at compound dot se I have run the Valgrind test with PHP 4.2.3 instead of 4.3.1. The 4.2.3 test produced none of the "Invalid write" messages that 4.3.1 produced. PHP 4.2.3 was built with an identical config-file as 4.3.1. Unfortunately I believe we upgraded from 4.2.3 to get rid of ODBC-problems... ------------------------------------------------------------------------ [2003-02-26 09:42:23] kalowsky@php.net sounds like a problem on my end... icky... ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
