一、漏洞信息
漏洞编号:CVE-2023-25136
漏洞归属组件:openssh
漏洞归属的版本:8.2p1,8.8p1,9.1p1
CVSS V3.0分值:
BaseScore:9.8 Critical
Vector:CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
漏洞简述:
OpenSSH server (sshd) 9.1 introduced a double-free vulnerability during options.kex_algorithms handling. This is fixed in OpenSSH 9.2. The double free can be triggered by an unauthenticated attacker in the default configuration. One third-party report states remote code execution is theoretically possible.
