The following query causes a buffer overflow in the NGQP module. Any query with a single table in the FROM clause that may use more than four fields of a PRIMARY KEY or UNIQUE index is similarly vulnerable. CREATE TABLE t1(a,b,c,d,e, PRIMARY KEY(a,b,c,d,e)); SELECT * FROM t1 WHERE a=? AND b=? AND c=? AND d=? AND e=?; 3.8.0 is the only version with this bug. Earlier versions are Ok. | ||||
