CentOS 5.10 rpm을 CentOS 5.8에 설치해도 되나요?

이번에 CVE-6271 (ShellShock), CVE-7169 (AfterShock)에 대한 패치로
centos 5 버전에 대해서는 bash-3.2-33.el5_10.4가 나왔는데요,

아래 패치에 대한 설명에 궁금한 점이 있습니다.

Q1) 보통 CentOS 5에서는 bash-3.2-33.el5_10.4을 설치하라고 하는데 원래 하위 버전은 상관이 없나요?

Q2) 아래 설명을 보면 5.11도 나온다고 하는데.. 그럼 5.11 사용자는 5.10으로 업데이트 하고 있다가
나중에 5.11이 나오면 다시 5.11로 업데이트 하라는 뜻인가요?

Note:  The above RPMS, built with the ".el5_10" dist tag are built
against CentoS-5.10 for CentOS-5.10.  The source code was not modified,
but the packages in the build root are the current CentOS-5.10 packages.

There is also a set of packages built against the upcoming CentOS-5.11
with a ".el5_11" dist tag that will be an upgrade when 5.11 is released
and all the packages in that build root are from the upcoming
CentOS-5.11 release.  The ".el5_11" announcement and package will be
done as a zero-day update to CentOS-5.11.

We wanted to get the Important bash update out for 5.10 while also
getting the proper packages out for 5.11 as well, so this was the solution.

Thanks,
