CVE-2019-19126 Open this link in a new tabHow to fix?
Upgrade Oracle:8 glibc-minimal-langpack to version 0:2.28-101.0.1.el8 or higher.
This issue was patched in ELSA-2020-1828.
NVD Description
Note: Versions mentioned in the description apply only to the upstream glibc-minimal-langpack package and not the glibc-minimal-langpack package as distributed by Oracle.
See How to fix? for Oracle:8 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.
