## 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.
