[原文]Buffer overflows in (1) circle_poly, (2) path_encode and (3) path_add (also incorrectly identified as path_addr) for PostgreSQL 7.2.3 and earlier allow attackers to cause a denial of service and possibly execute arbitrary code, possibly as a result of an integer overflow.


[CNNVD]PostgreSQL path_encode()缓冲区溢出漏洞(CNNVD-200301-029)

        
        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的'path_encode()'函数对用户提交的输入缺少正确检查,本地攻击者可以利用这个漏洞进行缓冲区溢出攻击,可能以PostgreSQL进程权限在系统上执行任意指令。
        'src/backend/adt/utils/geo_ops.c'中的'path_encode()'函数对用户提交的字符串缺少正确缓冲区边界检查,超长的字符串可导致覆盖程序指令指针,精心构建提交数据可能以PostgreSQL进程权限在系统上执行任意指令。
