CVE-2019-19126  (opens in a new tab)
CWE-20  (opens in a new tab)

How to fix?

Upgrade Centos:7 glibc-common to version 0:2.17-317.el7 or higher.

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:7 relevant fixed versions and status.

On the x86-64 architecture, the GNU C Library (aka glibc) before 2.31 fails to ignore the LD_PREFER_MAP_32BIT_EXEC environment variable during program execution after a security transition, allowing local attackers to restrict the possible mapping addresses for loaded libraries and thus bypass ASLR for a setuid program.
