CVE-2018-1000001 Open this link in a new tabHow to fix?
There is no fixed version for Centos:6 glibc-common.
NVD Description
Note: Versions mentioned in the description apply only to the upstream glibc-common package and not the glibc-common package as distributed by Centos.
See How to fix? for Centos:6 relevant fixed versions and status.
In glibc 2.26 and earlier there is confusion in the usage of getcwd() by realpath() which can be used to write before the destination buffer leading to a buffer underflow and potential code execution.
