为什么没有可用的内核升级(Debian Wheezy)

为什么没有可用的内核升级(Debian Wheezy)

我正在尝试修补一个我已确认易受肮脏 COW 攻击的服务器。那里有许多其他指南推荐以下内容,但没有可用的软件包。

# uname -rv
3.2.0-4-amd64 #1 SMP Debian 3.2.41-2+deb7u2

我遗漏了什么?在我看来,我正在访问 wheezy 的安全更新存储库。

更新:

看起来我读的是软件包名称而不是内核版本号:

# apt-cache policy linux-image-3.2.0-4-amd64 linux-image-amd64
linux-image-3.2.0-4-amd64:
  Installed: 3.2.82-1
  Candidate: 3.2.82-1
  Version table:
 *** 3.2.82-1 0
        500 http://security.debian.org/ wheezy/updates/main amd64 Packages
        100 /var/lib/dpkg/status
     3.2.78-1 0
        500 http://httpredir.debian.org/debian/ wheezy/main amd64 Packages
linux-image-amd64:
  Installed: 3.2+46
  Candidate: 3.2+46
  Version table:

        500 http://httpredir.debian.org/debian/ wheezy/main amd64 Packages
        100 /var/lib/dpkg/status

话虽如此,uname -ir即使重新启动后仍然显示以下内容:

# uname -ir
3.2.0-4-amd64 unknown

答案1

Ondra Sniper Flidr 的回应暗示,当这个问题于 2016 年 10 月底发布时,Wheezy 已经停止服务了。

事实并非如此:直到 2018 年 5 月底,Wheezy 仍通过 Debian 的长期支持计划继续获得安全更新和社区支持。

Wheezy 的官方 LTS 存储库确实发布了针对 Dirty COW 的补丁。

答案2

这是因为 Debian Wheezy 已经过了使用寿命,并且不再受到 Debian 社区的支持,所以这里没有更新(至少没有来自官方存储库的更新)。
