一、漏洞信息
漏洞编号：CVE-2023-38545
漏洞归属组件：mysql
漏洞归属的版本：8.0.17,8.0.23,8.0.24,8.0.26,8.0.27,8.0.28,8.0.29,8.0.30,8.0.35,8.0.37
CVSS V3.0分值：
BaseScore：9.8 High
Vector：CVSS：3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
漏洞简述：
This flaw makes curl overflow a heap based buffer in the SOCKS5 proxyhandshake.When curl is asked to pass along the host name to the SOCKS5 proxy to allowthat to resolve the address instead of it getting done by curl itself, themaximum length that host name can be is 255 bytes.If the host name is detected to be longer, curl switches to local nameresolving and instead passes on the resolved address only. Due to this bug,the local variable that means let the host resolve the name could get thewrong value during a slow SOCKS5 handshake, and contrary to the intention,copy the too long host name to the target buffer instead of copying just theresolved address there.The target buffer being a heap based buffer, and the host name coming from theURL that curl has been told to operate with.
