低危 GNU Wget缓冲区溢出漏洞
CVE编号
CVE-2017-13090利用情况
暂无补丁情况
官方补丁披露时间
2017-10-28漏洞描述
在处理OK响应时调用retr.c:fd_read_body()函数。当响应在1.19.2之前以块的形式在wget中发送时，块解析器使用strtol()读取每个块的长度，但不检查块的长度是否为非负数。然后，代码尝试使用MIN()宏以8192字节为单位读取块，但是最终将负块长度传递给retr.c:fd_read()。当fd_read()接受一个int参数时，块长度的高32位被丢弃，留下fd_read()一个完全由攻击者控制的长度参数。攻击者可以在分配缓冲区之后破坏malloc元数据。解决建议
