Subject: [PATCH] Fixed Bug #64949 (Buffer overflow in _pdo_pgsql_error)
|
|
|
2067da |
|
|
|
2067da |
There is a lot of call such as:
|
|
|
2067da |
pdo_pgsql_error(dbh, PGRES_FATAL_ERROR, "Copy command failed");
|
|
|
2067da |
Where the 3rd paramater is a error message string where a sqlstate (5 chars)
|
|
|
2067da |
is expected. This cause a segfault in copy_from.phpt and copy_to.phpt.
|
|
|
2067da |
|
|
|
2067da |
This is only a sanity check to avoid buffer overflow, but obviously this
|
|
|
2067da |
calls need to be fixed (using NULL or a correct sqlstate).
