[原文]Buffer overflows in the (1) TZ and (2) SET TIME ZONE enivronment variables for PostgreSQL 7.2.1 and earlier allow local users to cause a denial of service and possibly execute arbitrary code.


[CNNVD]PostgreSQL TZ环境变量缓冲区溢出漏洞(CNNVD-200301-024)

        
        PostgreSQL是一款增强型对象-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在处理TZ环境变量时存在漏洞,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。
        PostgreSQL在处理超长TZ环境变量可触发缓冲区溢出,精心构建TZ环境变量数据,本地用户可以对系统进行拒绝服务或以PostgreSQL进程权限在系统上执行任意指令。
