CVE-2024-7589

一、漏洞信息
 漏洞编号：[CVE-2024-7589](https://nvd.nist.gov/vuln/detail/CVE-2024-7589)
 漏洞归属组件：[openssh](https://gitee.com/src-openeuler/openssh)
 漏洞归属的版本：8.2p1,8.8p1,9.1p1,9.3p1,9.3p2
 CVSS V3.0分值：
  BaseScore：8.1 High
  Vector：CVSS：3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
 漏洞简述：
  A signal handler in sshd(8) may call a logging function that is not async-signal-safe.  The signal handler is invoked when a client does not authenticate within the LoginGraceTime seconds (120 by default).  This signal handler executes in the context of the sshd(8) s privileged code, which is not sandboxed and runs with full root privileges.This issue is another instance of the problem in CVE-2024-6387 addressed by FreeBSD-SA-24:04.openssh.  The faulty code in this case is from the integration of blacklistd in OpenSSH in FreeBSD.As a result of calling functions that are not async-signal-safe in the privileged sshd(8) context, a race condition exists that a determined attacker may be able to exploit to allow an unauthenticated remote code execution as root.
