[原文]Heap-based buffer overflow in the repeat() function for PostgreSQL before 7.2.2 allows attackers to execute arbitrary code by causing repeat() to generate a large string.


[CNNVD]PostgreSQL Repeat函数本地缓冲区溢出漏洞(CNNVD-200301-033)

        
        PostgreSQL是一款增强对象-关系数据库管理程序,支持SQL标准子集扩展,适用于多种操作系统下。
        PostgreSQL repeat函数对用户提交的输入缺少正确处理,本地攻击者可以利用这个漏洞进行缓冲区溢出攻击,导致权限提升。
        repeat()函数对参数缺少正确的缓冲区边界检查,提供超长参数可以导致产生缓冲区溢出,以数据库进程权限在系统执行任意指令。
