Commit message: fixed fix #69975 wrt. ODBCVER < 0x0300
CVE: CVE-2015-8879
CWE: CWE-20
Vulnerability description: The odbc_bindcols function in ext/odbc/php_odbc.c in PHP before 5.6.12 mishandles driver behavior for SQL_WVARCHAR columns, which allows remote attackers to cause a denial of service (application crash) in opportunistic circumstances by leveraging use of the odbc_fetch_array function to access a certain type of Microsoft SQL Server table.
