Operating system: Debian 5.0 "Lenny" AMD64
PHP version: 5.2CVS-2009-05-08 (CVS)
PHP Bug Type: ODBC related
Bug description: ODBC crash from PHP
Description:
------------
ODBC crashes when using php script included (using a MySQL database), and
an
ALERT - canary mismatch on efree() - heap overflow detected (attacker
'X.X.X.X', etc ...)
line pops up in the error.log for apache.
This happens on current stable Debian 5.0 "lenny" AMD64, with system up to
date as of today, running: apache2, php5, mysql-server.
Compiling latest MySQL odbc driver version 5.1.5 doesn't crash, but does
lock up the calling process if same script is run with php5 client from
command line.
Reproduce code:
---------------
$conn="DRIVER={MySQL}; DatabaseName='test';
CommLinks=tcpip(Host=localhost); ";
$conn=odbc_connect($conn, "user", "");
$sql='SELECT * FROM test.T1;';
echo $sql;
$pg_query=odbc_exec($pg_conn, $sql);
odbc_close($pg_conn);
echo "A";
