zx900930 1. 对于 FreeBSD 是否受影响,既是,亦否:
https://forums.freebsd.org/threads/ssh-cve-2024-6387.94018/“And no, the RCE that makes this an actual threat does not apply to FreeBSD (or other BSDs and illumos), but only to systems using gnu libc”
直接下定论说“FreeBSD 可是完全在影响范围内的”为时过早,甚至未必是正确结论(如果事后证明该漏洞没有 impact 到 FreeBSD 的话)。
昨天 opnsense 社区已经有人提到了 FreeBSD Security Team 为什么会发布漏洞,简单来说单纯就是“没发现冲击,不管怎样,先升级了再说”:
https://forum.opnsense.org/index.php?topic=41342.0“There's no confirmation yet on FreeBSD, however the security team there decided they'll patch first and ask questions later - as Colin explained it on Twitter shortly after the vulnerability bacame public.”
对应推特原文:
https://x.com/cperciva/status/1807703216567865471“unclear if exploitable on FreeBSD but we have an advisory out just in case.”
没错,just in case ,就是这么简单粗暴
于是才有了
https://www.freebsd.org/security/advisories/FreeBSD-SA-24:04.openssh.asc2. 我原文写的是“这就是为什么 OpenBSD 本身没事”,这么清楚的描述还能理解成“连带 Linux 都没事”,我觉得实在是匪夷所思。
