[原文]The (1) to_char and (2) to_date function in IBM DB2 8.1 allows local users to cause a denial of service (application crash) via an empty string in the second parameter, which causes a null pointer dereference.


[CNNVD]IBM DB2 to_char和to_date函数本地拒绝服务漏洞(CNNVD-200512-855)

        IBM DB2是一个大型的商业关系数据库系统,面向电子商务、商业资讯、内容管理、客户关系管理等应用,可运行于AIX、HP-UX、Linux、Solaris、Windows等系统。
        IBM DB2在处理to_char和to_date函数调用时存在问题,本地攻击者可以利用这个漏洞对服务进行拒绝服务攻击。
        如果to_char函数调用空字符串给第二个参数,DB2就会废弃一个NULL指针而停止:
        select to_char('aaa','') from sysibm.sysdummy1
        如果to_date函数调用空字符串给第二个参数,DB2就会废弃一个NULL指针而停止:
        select to_date('aaa', '') from sysibm.sysdummy1
        需要重新启动获得正常功能。

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
