Bug #61212 [NEW]: PDO ODBC Segfaults on SQL_SUCESS_WITH_INFO
From:
Operating system: Linux
PHP version: 5.3.10
Package: PDO related
Bug Type: Bug
Bug description:PDO ODBC Segfaults on SQL_SUCESS_WITH_INFO
Description:
------------
PDO ODBC segfaults when a column less than 256 bytes are retrieved (has to
be SUCCESS_WITH_INFO). The buffer is allocated with the assumption the
retrieved column is greater than 256 bytes. When a column with say 150
bytes are allocated, the code tries to write 256 bytes to the buffer and
results in a segfault.
The segfaults go away by ensuring the column length is checked before
assigning characters to the buffer.
Test script:
---------------
<requires a column coming from the db with a character encoding issue and
length less than 256>
Expected result:
----------------
Should work regardless of the length of the column data
Actual result:
--------------
Segmentation Fault
