glibc 의존성 질문드립니다.

안녕하세요

glibc 취약점 관련하여 패치를 진행하는 과정중 의존성 

때문에 문의드릴께 있어서 이렇게 글을 남깁니다.

제 OS 환경은 다음과 같습니다.

OS 환경 : centos 6.2 / 64bit
glibc: glibc-2.12-1.149.el6_6.5

공식 홈피에서 다운로드 glibc-2.12-1.166.el6_7.7.x86_64 버전으로 설치를 진행하면 

의존성이 발생하여 설치 불가능하고 nodeps 명령어를 하면 강제로 설치하면 되긴하나

다른 어떠한 문제가 발생할지 모르는 상황인지라..망설이기 되네요.

에러는 아래와 같이 발생하네요. 고수님들 답변을 부탁드립니다.
