低危 LibCurl IMAP响应处理不当导致缓冲区溢出漏洞
CVE编号
CVE-2017-1000257利用情况
暂无补丁情况
官方补丁披露时间
2017-11-01漏洞描述
IMAP FETCH响应行以字节数表示返回数据的大小。当该响应表明数据是零字节时，libcurl会使用指针传递该(不存在的)数据，并将大小(零)传递给传递数据函数。 libcurl的deliver-data函数将零视为magic number，并在数据上调用strlen()来计算长度。 strlen()在基于堆的缓冲区上调用，该缓冲区可能不会被终止，因此libcurl可能会读取超出其结尾的内存(或者只是崩溃)，然后将其传递给应用程序，就像它实际上已下载一样。解决建议
